Must say, I am in total agreement with Kegs - for many many years, my diabetes regime was very hit and miss. What to eat, when to eat and how much insulin to inject was all very much finger in the air stuff and hardly any blood glucose testing at all. It was the embarrassment of hypos at work and hypos at night after exercise which led me to agreeing to attend a DAFNE course - and that totally changed my life!
Attendance on the DAFNE course was a pre-requisite for anyone considering a pump in my area. I am now carb counting and testing as often as Kegs - and am also obsessive about my whole diabetes regime. This is a total turn around from how I was for more than a couple of decades!
It is very well worth noting the points made above though. Using an insulin pump requires a lot of attention and a commitment to blood glucose testing and carb counting - all alongside an understanding of how everything interacts. I suggest that you discuss the criteria that your care trust use when deciding who to provide with pump therapy. In my case, these criteria included attendance on a DAFNE course but yours may - and most likely will - be totally different.
