memali26:You need to take it before you eat so that it has a chance to do it's job. I'm on Humalog with every meal and my endo recommends taking it about 15 minutes before eating.
I'm on Humalog too, before lunch. They told me it starts working in 15min but didn't tell me exactly when to take it. I make my lunch, take my insulin and then eat (I don't wait 15min).
