To be fair, my basal is actually okay over night. The main issue for me is that I like to eat late (or just end up doing so when stuck at work) and hate the fact that if I go to bed within a couple of hours after eating I'm not confident if I over or under estimated my bolus shots. I also used to enjoy a snack at night but find that more difficult now.The funny thing is that my nights are very easy to predict how my BG level will operate since I changed to Levemir. On Lantus I had much less predictability and it does affect sleep.
