Hi Micky.
Welcome.
See you are a fellow 'lizard spit' user. there are a number of us on here. Check out the 'Anyone Use Byetta' threads. Loads of information. You could also just do a search on Byetta top right and all will be revealed. Most questions have been answered previously.
If you do have any questions, even repeats, just ask, we will always answer.
Ken.
