Im not too far behind you yingtong in living with type 1.
Not sure whether you will like pumping or whether youll see all the warts and corns after youvr had a pump for about a year. There have been times when Ive been only too grateful to use a pen to sort out really high bg levels rather than rely on the pump and worry if it is working as it should. Youve got to keep your wits about you and test bg levels a lot more than on MDI. The good thing, even with all the agro that pumps are at times, is that youll be able to go to sleep at night and not worry about going hypo p and needing help to get out of them.
Have a good read up on the forums as most problems have been discussed so good luck...
