oh and one last question..with MDIs my short acting is novorapid, and I understand with the pump one type of insulin is used in the cartridge for both bolusing and basal rates. With MDIs there's a waiting period of 2 hours or so after eating whereby you can't eat any carbs until the insulin 'peak' has lowered and sufficiently completed its processes ( and the insulin leaves the system after 5 hours). With the pump, I've read that it's possible to tweak basal rates with boluses so the 'eating window' can be more spread out? any pointers on this topic would also be appreciated
