I'm a type 1 diabetic and started using Humalog when I started using an insulin pump nine years ago (after many years of injections with other insulins). It has made a huge difference in managing blood sugar levels. Unlike other insulins, Humalog is extremely fast-acting. You can take tiny doses at a time and it works almost immediately. That allows you to fine-tune your blood sugar levels in ways that aren't possible with other insulins. I'm only familiar with how it works with the pump, but I highly recommend Humalog and pumping to other type 1's, particularly those who have trouble with blood sugar control or just want more flexibility in their day.
