I am responding to the most recent post about Zocor side effects. Yes, I had the same response about not being believed about the side effects that I was experiencing. One of the most troublesome for me was the depression to the point that I was teary every day. Slowly, this seems to be lifting-I have been off the Zocor approximately 8 weeks. I also experienced the eye twitching that was so severe it interferred with my everyday life. Also, I had breathing difficulties with chest pain.
