Most endos won't put someone without good control on a pump, with good reason. Pumping requires a high amount of diligence, frequent testing and carb counting. Plus going from poor control to the lower bgs, that often arise in the beginning of pump use, quickly can often lead to more complications. With your busy lifestyle I do agree a pump would be more convenient. However you really do need to be in fairly good, though not great, control beforehand. And you will need to show your endo, if you haven't already, that you have a high level of commitment. In the year leading up to my starting the pump I had to be very diligent about keeping logs, which was tough for me. I am a terrible log keeper, but with GB I am actually beginning to be a good one.
Good luck!
