Hi crawford.
That's great that you have lost the weight - just shows what a good thing Byetta is. Keep going with it unless you are at your ideal weight ?
As for the stall in weight loss this sometimes happens for a little while and can then kick back in again. May also be due to a change in things you are eating now ? You do say you are eating more ?
Injection times are an individual thing, I was told to inject and wait about half an hour before eating, others inject and eat straight away. I don't suffer any nausea at all and never have. It is not a foregone conclusion that you will feel sick because you change the time you inject - try it and see.
Byetta has a side effect that it suppresses the appetite as well so I am not surprised you have 'gone off things.' I never feel hungry at all and have to make a point of eating when I should. One of the side effects is that it can affect your taste buds - not heard about smell though ?
One other thing is if you do a search top right for Byetta you will get over a 1000 posts which may answer some of your questions - if not ask away.
Hope that helps.
Ken.
