I,m new to this site. I was diagnosed type 2, three years ago. I'm allergic to metformin and have tried various medications during that time. I have been injecting Byetts for 3 and a half months and my glucose levels are very pleasing but I still feel nauseous every time I eat which lasts for a couple of hours at a time. When my levels dropped (they went from 9 to 26) I couldn't have been happier but I'm seriously thinking of ringing the diabetes unit and seeing if I can try something else.
