For Type 2 Diabetes "I have been off and on Byetta for about 2 years. I had issues with vomiting and not being able to tolerate the 10 mg. Finally, I found the answer. My doctor said to take the injection, then wait 1 full hour to eat, and not to eat more than a very, very small portion of food. I have not had any upset stomach doing this. I thought it was because of what I ate, like salad dressing or greasy foods, but it was the amount of food that I ate that was making me sick. I haven't been sick this round of using the medicines, using this method, and feeling very full after just a few bites of food. Try limiting your food intake to relieve stomach upset."

For Type 2 Diabetes "The first week of Byetta 5 mcg dose, no side effects, 6-pound weight loss but high blood glucose numbers. My endocrinologist suggested I try going up to the 10 mcg dose. Nausea, gas, stomach upset, and constipation. I ended up in bed most afternoons. Numbers are now good, and I've lost another 4 pounds. Too much lifestyle impairment due to side effects, so I went back to the lower dose, still having stomach aches and constipation. I'm giving it time, but so far this has been an uncomfortable experience."
