I don't think anyone can tell us how long the damage from taking a statin will remain with us because for each person it is totally different. The actual drug may be out of our bodies within a few weeks, but the damage it has done in my opinion is pretty much there for the duration.
This past year I have had a big turnaround, but I have been off Lipitor for almost 4 yrs now (10/28/2004) and thanks to a Wellness doctor I went to 8/2007 I am able to do most things that I could not do before that i.e. walk, use my arms to lift/carry, think straight and so forth.
However, should I take one too many supplements that pain and weakness returns...I think once we find we are feeling pretty good we are unable to even fine tune things and we have a slight relapse - at least that is how it is for me. Also, what amount of supplements and type of supplements works for me I feel would not be the totally correct amount to help the next person.
I doubt anyone will be able to ever find a cure that would be suited for every person with statin damage and they say "take this one pill and you will feel better".
