Soon after starting Byetta my A1C also dropped below 6.0 for the first time. Since then it's never been higher, and my most recent test was 4.8.
Full disclosure: I own stock in Amylin, which developed and sells Byetta.
For me, knowing that I could control my A1C, my weight, and therefore my diabetes was the key to motivating me to do what I knew I had to do. When I had thought that it was too hard for me to control my weight, I made only short-lived efforts. I needed this positive motivation to get on track.
Are you controlling your diabetes too? If you are, what motivated you?
