I am about to start using Byetta (Exenatide). Which is a twice daily injection half an hour or so before breakfast and dinner, for much the same reasons as you. However, my doc won't put me on insulin, yet, as he was concerned that I might put on too much weight. This can be a problem for Type 2 on insulin, so I have been told.
As said before, Bydureon is the same medication, but a once a week injection, apparently the weekly on is not suitable for people with heart problems, like me.
If you do get put on Bydureon, I would be interested to see how you get on.
Best wishes
