I recently had an extremely bad case of depression. I could not figure out what was wrong with me. I could not stop crying. It took me 2 month to figure out that my depressive episode coincided with my doctor putting me on 20mg simvistatin(generic zocor). I've been off of it for 5 days now and have already seen a dramatic improvement. I will never take cholesterol lowering meds as long as I live, I don't care if my cholesterol is 500.
