After taking Lipitor for approx. 6 months I began having pain across my shoulders and neck and after a few weeks started to feel very tired and weak. It became an effort to get out of bed - all I wanted to do was sleep. I saw my doctor who took four vials of blood and did all sorts of tests with the results that everything was normal. He never brought up the subject of Lipitor or that it might be the problem. I then heard about this web site from my sister who is an RN and very much against the statin drugs. She encouraged me to give up the Lipitor and increase the vitamin C that I already take. I have only been taking 5 mg as a starter but wonder what would have happened if I was taking more.
