Are you looking for help on the matter? If so, please tell us more about the specific times it is happening.
How long before/after your first bite do you inject insulin?
Does this happen during particular times of the day?
Also, which type of Humalog are you using? (u100, u200, 75/25, 50/50, etc)
Those are all extremely important variables to consider in helping you.
Side note: if you have type 1 (and low insulin resistance) it would actually make you MORE likely to respond to insulin rather than less likely.
