There is a lot of metformin info here:

Metformin for type 1s

i saw my endo on tuesday where we talked about my sugar levels and how they are doing, where my a1c is (7.4%), and about my weight which ive been gaining instead of losing as i thought i was doing. so he put me on metformin which ive thought for years were for type 2s for insulin sensitivity and to help with my weight. i am also on the animas pump which has been great since 2010. so has any other type 1s on metformin? your experience, advice, etc? i took my first pill last night

One of the big reasons I take it is for my heart. But there are a lot of other reasons.
