Simvastatin and upset stomach

I have been taking simvastatin since June 28, 2008. I am 44 years old and have always been majorly active with my 17 year old daughter. Recently I have become chronically fatigued so much as to want to go back to bed within 2-3 hours after I get up in the morning, (definitely not me). I have felt spaced out,depressed to the point of wanting to cry all the time, have severe back, hip, knee, leg, and hand pain. I go to pain management for my back and hip problems (past surgery), but the usual pain has been intensified over the last 2 months and I wasn't sure why, until i decided to check out the Simvastatin to see if it has made me put on a few pounds, and boy have my eyes been opened!!!!!!!!! I AM STOPPING THE MEDICATION IMMEDIATELY!!!!!!!!!!!! Thanks to all who have spoken up, I wish I would of checked on this sooner!!!!! I'm calling my Dr. first thing in the morning!!!!!!!!!!!

I went on Simvastatin 40mgs last Christmas 2007 because of the family history of strokes, I was generally feeling very well .
Since being on statins I have felt awful , with lots of side effects " muscle cramps, upset stomach, really really tired, strange feelings in my chest and bad palpations "... I thought I was really ill.which made me very depressed.and even had test's done at the hospital to try and find what is wrong with me thankfully nothing appears to be seriously wrong" so why feel so dreadful i thought it had to be the statins!!"
I came off them my self four weeks ago ,since then I have been to see my doctor who has agreed for the time being I should be off simvastatin but consider taking a milder statin.
I do feel slightly better after four weeks ,but still get some of the side effects can any one suggest roughly how long it takes to feel like one's old self again.....Please!!!
