Started on Byetta, 10mcg, one week ago. Prior, my levels in the am were between 110 and 120. After starting the Byetta, by fasting glucose is up to 145 to 160 in the morning. Yes, taking the Byetta will get it down to 130. But I am wondering why they would be so much higher? I took Byetta several years ago and my fasting levels would always be below 100. What's going on? Any suggestions or comments?
