Hi Acient Lady
I do pump but sadly not the Animas but with a Accu-Chek spirit pump but they all do have the same priciples but yours will have some better features than mine...
Don't worry about going straight onto insulin, I did this and drove home and back again the next day... the trainer/diabetic nurse will let you know what to do about your back ground insulin before hand... And they will ask for your last several days of TDD (all the insulin both basal and bouls that you've taken) they will use this to work out a basal rate (normaly a flat profile rate xx amount every hour)that shouldn't let you go to low or too high to start....
I must admit that I was a little apprehensive when they told me that this is what they were going to do, but at the end of the day I think I peferred it, as if you spend say a week or even a couple of days using saline in the pump, you then got the injections to do and the faffing with the pump... and you'll still be starting on the flat rate proflie they set to start...
