Nausea is the most common side effect and tends to hit hardest in the first few weeks after each dose increase, improving as your body gets used to it. On the days when solid food just won’t go down, these are usually better tolerated:
Plain yogurt, eggs, oatmeal, banana, broth-based soup, potatoes, rice. A protein shake can sometimes go down easier than a full meal.
Water-rich fruits and vegetables like watermelon, cucumber, and tomato help when dry foods make you nauseous.
Avoid fried foods and very fatty dishes on those days: they stay longer in an already slow stomach and make the feeling worse.
If vomiting is severe and won’t stop, or if you have strong abdominal pain, that is not "part of the process": talk to your doctor. This is information to help you understand what you’re experiencing; it does not replace your doctor. Your doctor is the one who adjusts the pen, dose, and treatment plan.
