Slow acting or fast acting insulin. I went on slow acting last year or so. One shot in the evening. My fasting (7 AM) is about 120 and below. Mine hasn't been too good A1C about 7.5. I'm moving my evening shot up to about 3 PM. I also don't eat breakfast, a light lunch and a medium sized dinner. My doc also wants to put me on fast acting insulin. I currently take 3 metformin and 1 Glyburide (1 & 1 in AM, 2x in PM).

All I can do is commiserate with you.
