I am 38 y/o male on Zocor for over 7 years. Had heart attack @ age 32. Cardiologist put me on Zocor immediately. Have experienced just about every problem mentioned on this site. Took 20 mg for first 6 yrs., Dr. upped to 40 mg. recently. Memory has not been the same since getting on this product. Has affected short term memory from day 1., which in turn has made college course work and other work related activities even that much more challenging. Have severe pain on left lower leg and other numerous muscle aches. Most noteably, getting up in the mornings and getting out of bed are a tremendous challenge. Once up for 15 mins. + I start feeling more like my old self. Never felt like this before taking this product. Tired of aching all over and losing ability to communicate/ pronounce words or forgetting words all together.
