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?
