I use Humalog and I'm the happier with it than I have been with Toronto (Regular). It starts working very quickly and brings down highs much quicker. (From what I hear, Novolag is similar, but does not begin to act quite as quickly.) Not only that, Humalog leaves the body fairly quickly.
I started pumping yesterday, and I'm still using Humalog. Prior to that, I took Humalog as a mealtime bolus dose as well as sometimes using it as a correction bolus.
Try it! I think you'll like it!
