Hi, Linda, welcome to the forum!
I was on Byetta for a short time. I started on the 5 pen in June. It wasn't really doing anything so the doc put me on the 10 in July. I couldn't tolerate it...vomiting, diarrhea, the works. I lost 10 lbs. in a week but that was most definitely the hard way. :( So I went back on the 5, but I still didn't see any real improvement in my numbers or my weight loss. Then in August I stumbled on to this forum...and through the wonderful information disseminated here, I learned how to eat. Since June I've lost over 30 lbs., my numbers for everything are down and I have lost the weight around the middle. And I've gone off the byetta.
What I learned was that you pretty much as a diabetic (although this actually works well for others. too. at my husband will attest), have to eliminate most carbs from your diet. What have you been eating, what are your sugars like? Are you exercising? (I'm still working on that one myself.) What I have noticed from other byetta blogs and forums is that many people on the byetta expect it to do all the work without changing their lifestyle or habits much. Carbs are the literal killers for diabetics. All white flour, rice, potatoes, cereals (except for maybe old-fashioned oatmeal), and of course, sugar all have to be eliminated. Jeannie, the forum moderator, calls it the no white food except cauliflower diet. Lots, of vegetables, protein and the right fats (olive oil, canola oil, nuts, avocado). Due to the high sugar content in fruit, even that has to be eaten sparingly. South Beach is a pretty good diet, although there are still too many carbs for me personally. And there is a great book called The Diabetes Solution by Dr. Richard K. Bernstein, that really educates a person on how to change her lifestyle to control diabetes. I found it on Amazon but I'm sure you can get it at other bookstores. And if you google him, there is a website devoted to him that has many of his chapters right there on the site for people to read. You will no doubt hear from many others on how to eat to help control your diabetes. Listen to them. They totally have some great suggestions. Good luck and keep us posted.
