Heck, I was even using NPH instead of Lantus because I could never get Lantus to work right for me. Even so, my two NPH shots plus
sliding-
scale Humalog worked very well.
And I work out (aerobic and weight lifting) religiously.
The tight control changed as my metabolism changed in my early 30s. I'm 32 now and things just went a little whacky, for lack of a better word. I tried (like hell) to get things back under control, but I just couldn't do it.
