Criminal act symptoms and conditions

I have had Type 1 Diabetes for many years (54) without any complications of the disease - until I had a mild stroke. Which didn't affect me. Now my doctor makes me take Lipitor. From the very start of taking 10mg Lipitor per day, I got muscle cramps and leg twitches whilst in bed; muscle weaknesses; I even got Plantar Fasciitis and now I limp slightly in that foot. Before I took Lipitor I used to sleep like a baby. Lipitor has made me from a relatively healthy person despite having Diabetes to what feels like an old lady at aged 55. I know it is Lipitor as when I stop taking the drug all unpleasant side effects mentioned above cease. The trouble is my doctor won't give my Insulin without Lipitor and I need Insulin to live, of course. So I am forced to take Lipitor. I find that exercise such as a good long walk during the daytime helps; without it (eg in bad weather when I cannot get outside) the effects of Lipitor are much worse. My cholesterol readings and blood pressure are always good (even before the stroke) so why should I have to be almost crippled by Lipitor?
