Hi, good old Humilin M3 iam still on this diagnosed at 10 and nearly 23 years later still on it. I spose its not for everyone I like to be in routine but as for me as a child using M3 it was pretty much breakfast snack dinner snack tea snack then something to eat just before bed, if I did any sports id have a chocolate bar instead of adjusting my insulin all the time. Then for me I used to have a little extra M3 at evening as I wasn't as active at night. Then just slowly increased my insulin. By unit or 2 at a time. Like I said its not very flexible but ive always like to be in routine anyway.
