after reading the testimonials of so many people who have had problems with Zocor. I know I am going to stop taking it.I am 61 and have been on Zocor for 8 years. I was a healthy 53 when I had a stress related heart attack. Even the nurses told me I did not fit the heart patient profile and that I looked more like a 40 year old. My doctor put me on 10 mgs. of Zovor a day. About 2 years ago, I changed doctors and she increased my dose to 20 and then 40mgs. I have not been taking 40 mgs, I split the pill but I have experienced just about every side effect that I have read about today. The most noticeable are weakness, fatigue, headaches, fuzzy head, ears ringing, irratibility, vivid dreams, mostly bad dreams, and trouble sleeping even though I take Klonopin,and doxipin. I truly believe now that I have been on Zocor too long and probably a higher dosage than I need. My cholesterol is way below 200 about (140). I am so happy I found this Web site. Thanks to everyone for sharing your experiences, and thank you for the Web site
