I don't know much about using Byetta, but David Mendosa's site has several articles under "Medications", then "Byetta". I'd start there. He's also on Facebook, so you might be able to ask him questions. I don't know if he used both in combination, but I'm sure that using Byetta would be rather risky with insulin, as it makes digestion rather unpredictable. You might be able to use a basal insulin, but I think rapid insulins would just be too risky in combination with it.
