Simvastatin and sex drive

I am an active 60 year old.After being checked for diabetes I was told I was borderline and chose to try by changing my diet. Three months later at my next visit UI was told I was improved but my cholesterol was far too high and prescribed 40mg Simvastatin.Between then and the nest three monthly check I had numerous symptoms. My calfs throbbed, my shoulder ached and my sex drive decreased and I was always tired. The most frightening thing of all though was my concentration. I would be riding my motorbike or driving the car and suddenly snap to and realize my mind had been wondering and my concentration gone. (Ive had numerous near accidents.)
IU read on this site about "memory loss" and wondered if this was what was happening to me. My last three month visit was last week, my cholesterol is almost normal so I am stopping the pills and seeing what happens.

Started Simvastatin 20mg Jan. 08, just quit June 16th. I 've had all the problems the rest of you have had, arm, chest pain, thought I was having a heart attack for about a month, eye problems,no sex drive, memory loss, weird thoughts, stomach problems, so tired I could barely move, just could'nt wake up. Since I've been off this stuff I'm up one day and down another. I can see some progress, but it seems slow. Does anyone know how long it takes to get this stuff out of your system? Talked to a friend of mine who was on a statin, he quit , and told me it took him 6 months before he felt right. It does'nt seem to go away over night. Anyone else feel this way?
