| I take mine around midnight. I'm one of those 'dawn phenomenon' people. When I took it earlier at night, I would hit the hypos in the early a.m., but now all seems to be working fine.
I too love this insulin, the bedtime & morning NPH never seemed to cover my peaks at the right time, or I wasn't timing it right, but I'd usually have morning BGL in the 300-400 range, normal at lunchtime (sliding scale Humalog), but back into the 200's by dinner.
Since the switch to Lantus, I rarely get close to a 200 reading at any time of day. The key for me has been testing constantly to figure out when I need the peak and adjust the timing of the shot, but after that, its been smooth sailing throughout the day. |
