Going to start Byetta nxt wk for type 2 diabetes, did it work for u?

My sister takes Byetta and it has not caused her to loose weight. Partly how it works is that it makes you sick if you eat too much. She has a lot of problems with it because you have to take it so many minutes before you eat, and she works evenings and doesn’t always eat at the same time. She is going to ask for another medicine to take because if you eat too soon after taking it or eat too much, you feel sick for hours.
