been taking generic Zocor for about 2 wks, just 20 mg daily, right before bed. everything I read about this drug, says it lowers libido, and erection quality. not what I wanted to hear, since I have an existing problem. so I take it about 11pm, go to bed before midnite. almost every nite shortly after 1am I will awake and I am hard as a rock. and then again around dawn. so it's having an opposite effect on me?? or is it bringing cholesterol levels down so that my cock works as it always used to??? very weird, not that I'm complaining, nor is my wife. she's enjoyed a couple of these boners. in fact, I think she may be worried she's going have to start putting out daily. she's really not into sex anymore.
