I have to admit, I’ve been doing this for years. And most recently, my pump died, and I got a replacement. I was lazy and set up a basal with one rate for daytime, one for overnight. Before that I had 6 or 7 intervals. Total basal now 12, compared to 11.3.
Since I have CGMS, and feel lows pretty well, I plan on mini snacks throughout the day when trending low. The hardest part is over snacking, but then I just give bolus when I know I ate too much.
