I used Humalog or the equivalent Lilly brand fast acting insulin for 44 years. It was just call Regular, or R. I used their U-40 version for a while (only 40% as strong as their normal). I used Lilly brand NPH also. In 1996 Lilly released Humalog, which was faster, and I started using that one. That was a big deal.
Anyway, I used nothing but Lilly rapid insulin for 44 years until I started using a pump. After only 3 months on a pump I realized it was not really a good pump insulin and I switched to NovoLog.
The point is, I had an extremely long background of using Lilly insulin and nothing but Lilly insulin for a very long time, but when I saw problems I switched and am very glad I did.
So put aside whatever fear you have of NovoLog, or any loyalty you have with Humalog or whatever it might be, and just make the switch for a while and see what happens.
I can even send you some if you want. I have some very fine bottles in my special wine rack.
I don’t know why something is different now for you, but when you tried NovoLog, was it better than Humalog?
