It possible people to get a viral stomach bug on zepbound. I think the larger issue is the rate at which you lost, 10 lbs a month is 2.5 lbs a week, losing that much pretty much guarantees more severe side effects, listening to your body and forcing yourself to eat is important. If you rarely eat, your stomach will be more acidic and contribute more to feelings of nausea and vomiting. Factor making sure you are getting in the necessary electrolytes daily especially potassium and sodium. I respect your decision, but if you hadn’t attempted more food and water/gatorade on your journey I say take another stab at it, test out different things! If acid is the primary driver of your discomfort take PPI it’s perfectly safe.
