I am a female, age 54. I have been on 10 mg of Zocor for about six months. The first 3 months I didn't really notice anything but the past three I have gained at least 15 pounds, mostly right around the middle. I couldn't figure out why. It also increased my hunger or appetite. I couldn't control it, it was out of control. I was about to give up hope on why until I found this post. I'm quiting tomorrow!
