Week 1, Day 1. I took my last Wegovy injection at 8:15 AM on a Tuesday. 2.4 mg, subcutaneous, abdomen. I had been on it for 8 months. I had lost 18 pounds. My BMI had dropped from 28.1 to 26.4. I was not obese anymore. I was just overweight. And I was tired of the needles. Tired of the fridge logistics. Tired of the supply anxiety that had me calling three pharmacies every month to confirm my dose was in stock. So when Foundayo — orforglipron, Eli Lilly's once-daily oral GLP-1 — launched in April 2026, I made the switch. I kept a daily log. This is it. Unedited. Raw. The kind of data that does not make it into clinical trials.
Day 1 (Wednesday): First Foundayo pill. 12 mg, morning, with coffee. No nausea. Mild headache by 2 PM. Not sure if it is the pill or the anxiety of switching. Appetite normal at lunch. Ate a breakfast taco from Veracruz at 10 AM. Felt full by 10:45. That is unusual. Usually I am hungry again by 11:30. Maybe placebo. Maybe real. The data does not know. Weight: 182.4 lbs. BMI: 26.4. Baseline established.
Day 2: Headache gone. Appetite definitely suppressed. Ate half my usual lunch. Felt satisfied. Not stuffed. Just done. This is the GLP-1 effect kicking in faster than I expected. The oral formulation hits the stomach immediately, whereas the injection has a delayed onset. Pharmacokinetically, this makes sense. But experientially, it is disorienting. I am used to the gradual appetite suppression of semaglutide. The orforglipron effect is sharper. Weight: 181.9. Water fluctuation. Not meaningful.
Day 3: Nausea. Not severe. 3/10. Persistent. Lasted from 10 AM to 3 PM. Ate crackers. Drank ginger tea. Felt better by 4 PM. Dinner was light — soup and bread. The nausea is different from Wegovy. Wegovy nausea was episodic — sharp, brief, then gone. Foundayo nausea is a low-grade background hum. Like a fluorescent light you cannot turn off. Weight: 181.6. Still water.

This is the titration phase. The 12 mg starting dose is designed to acclimate the gut. But my gut is not acclimating. I called my doctor. She said: "Give it a week. If it is not better by day 7, we will lower the dose or add anti-nausea meds." I do not want to add meds. I want the data. Weight: 181.2. Dehydration from low intake. Not fat loss.
Day 5: The turning point. Nausea dropped to 2/10. Appetite returned but modified. I ate a normal breakfast — eggs, toast, coffee. Felt full for 4 hours. Lunch was a salad. Dinner was chicken and vegetables. Total calories: 1,680. Baseline pre-switch: 2,400. That is a 30% reduction without trying. The drug is doing the work. Weight: 180.8. Still mostly water and reduced glycogen. But the trend is moving.
Day 6: Energy is weird. Not low. Not high. Just different. Like my metabolism has shifted gears. I am not crashing at 3 PM anymore. The blood sugar stability from GLP-1 is real. No post-lunch slump. No 4 PM cookie craving. I worked until 7 PM without a break. That is not normal for me. Weight: 180.5. Trend continues.
Day 7: One week. Nausea is gone. Appetite is suppressed but manageable. I am eating 1,600-1,800 calories per day without hunger. My energy is stable. My sleep is slightly worse — I am waking up at 4 AM instead of 6 AM. Not sure if this is the drug or the excitement of the experiment. Weight: 180.1. Total loss: 2.3 pounds in 7 days. Mostly water. Some glycogen. Maybe a little fat. The trend is what matters. Week 1 summary: transition successful. Side effects manageable. Appetite suppression stronger than Wegovy at equivalent efficacy.

Monday morning: inject. The ritual was a reminder that I was on medication. It was medical. Clinical. Serious. With Foundayo, the ritual is daily. Morning. Coffee. Pill. It feels like taking a vitamin. Less medical. More mundane. I worry that the mundanity will reduce my psychological commitment. But the daily consistency might increase adherence. The data on oral vs injectable adherence is mixed. Some studies show better adherence for orals because they fit existing habits. Others show worse adherence because the daily requirement increases friction. I will know in 12 weeks.
Day 10: First social test. Dinner with friends at a restaurant on East 6th Street. I ordered an appetizer and a main. Ate half the main. Boxed the rest. No struggle. No willpower. Just not hungry. My friends noticed. "You are not eating," one said. I explained the switch. They had questions. I had answers. The conversation shifted from my plate to the drug. That is the social cost of GLP-1s. People notice. People judge. People ask. I am not secretive about it. But I am not evangelical either. It is medication. Not a lifestyle.
Day 12: Constipation. The classic GLP-1 side effect. Wegovy caused it too. But the oral seems worse. Maybe because the drug is in the gut longer? The injection delivers a bolus that is absorbed systemically. The pill dissolves in the stomach and bathes the gastric mucosa before absorption. The local effect on gut motility might be stronger. I added psyllium husk and increased water intake. Resolved by day 14. Weight: 179.2. The loss is slowing. Good. Fast loss is water. Slow loss is fat.
Day 14: Two weeks. Weight: 178.8. Total loss: 3.6 pounds. BMI: 25.9. I crossed from overweight to the high end of normal. Not that the categories matter. But the trend is encouraging. Side effects: minimal. Nausea gone. Constipation resolved. Energy stable. Sleep improving. Appetite suppression consistent. I am eating 1,700 calories per day without hunger. My BMR is 1,740. My TDEE is 2,650. I am in a 950-calorie daily deficit. The math says I should lose 1.9 pounds per week. Actual loss: 1.8 pounds per week. The math works. The drug works. The transition works.

No needles. No TSA issues. Took my dose in the hotel bathroom with tap water. It was so normal. So easy. With Wegovy, travel was a logistics operation. Ice packs. Cooler bags. Pharmacy calls. The mental overhead was real. The pill removes the overhead. I did not realize how much anxiety the injection logistics caused until they were gone.
Day 17: First missed dose. I woke up at 5 AM for an early flight. Took the pill. Forgot I had taken it. Took another at 7 AM. Double dose. Panic. Called my doctor. She said: "You will be fine. The drug has a wide therapeutic window. You might have extra nausea. Drink water. Eat light." She was right. Mild nausea for 4 hours. Then normal. The flexibility of the oral formulation is a double-edged sword. Easy to take. Easy to double-take. I set a phone reminder. Problem solved. Weight: 178.1. Trend continues.
Day 19: Energy is still weird. Not bad. Just different. I feel like my blood sugar is a flat line. No spikes. No crashes. Stable. Predictable. Boring. In a good way. I used to plan my day around meals. Now I plan meals around my day. The food is fuel, not the event. This is the GLP-1 mental shift. It is not just physiological. It is psychological. The drug changes your relationship with food. Some people find this liberating. Some find it disturbing. I find it efficient. Weight: 177.6. Slow and steady.
Day 21: Three weeks. Weight: 177.2. Total loss: 5.2 pounds. BMI: 25.7. The rate is 1.7 pounds per week. Slightly slower than week 2. As expected. The initial water loss is done. Now it is fat. I can feel it in my clothes. My jeans are looser. My belt is one notch tighter. The body composition scale — which is not perfectly accurate but directionally useful — shows body fat down 1.2 percentage points. Muscle mass stable. This is the ideal scenario. Fat loss without muscle loss. The drug is doing what it should.
Week 4, Day 22: The honeymoon is over. Appetite suppression is still present but less dramatic. I am eating 1,800-2,000 calories per day now. Not 1,600-1,700. The body is adapting. The GLP-1 receptor downregulates with chronic stimulation. The effect is still there. Just weaker. I expected this. The weight loss rate will slow. The key is to not compensate by eating more. I am tracking calories daily. The discipline is the drug. The drug is the discipline. They work together. Weight: 176.9. Small drop. Expected.

Just ate something she should not have. Again.) I wanted to eat my feelings. Pizza. Ice cream. The whole emotional eating playbook. But I was not hungry. The drug blocked the urge. Not by willpower. By physiology. I had a protein bar and went to bed. This is the hidden benefit of GLP-1s. They do not just reduce hunger. They reduce emotional eating. The gut-brain axis is real. And the drug is sitting right in the middle of it.
Day 28: Four weeks. Weight: 176.1. Total loss: 6.3 pounds. BMI: 25.5. The rate is 1.6 pounds per week. Consistent. Predictable. Sustainable. Side effects: minimal. Nausea: gone. Constipation: occasional, managed with fiber. Energy: stable. Sleep: good. Mood: good. Appetite: suppressed but not absent. I enjoy food. I just eat less of it. The transition is complete. I am an oral GLP-1 patient now. And the data says it was the right choice.
So here is my 28-day verdict. The switch from Wegovy to Foundayo was successful. The efficacy is comparable — slightly faster onset, slightly less dramatic peak, but same net result. The side effects were different — more nausea initially, more constipation, but shorter duration. The convenience is dramatically better. No needles. No fridge. No travel logistics. The adherence is easier. The daily habit anchors faster than the weekly ritual. The psychological shift is real. The relationship with food changes. The relationship with medication changes. It becomes normal. Routine. Boring. And boring is good in medicine. Boring means it works without drama.
I will keep the log open. I will keep tracking daily. I will keep updating the spreadsheet. Because the 28-day data is just the beginning. The real test is 6 months. 12 months. 2 years. The real test is whether the oral formulation maintains efficacy over time, whether the convenience translates to long-term adherence, whether the side effects remain manageable. The clinical trials say yes. My n=1 says yes so far. But n=1 is not data. It is a story. And I will keep telling it, one day at a time, one pill at a time, one spreadsheet row at a time. Because the data is the only thing that does not lie. And the data says the switch worked.
