Zocor and difficulty breathing

44 yr old white male in excellent physical condition. Dx'd last yr w total chol of 290 and elevated liver enzyme, probable fatty liver disease. I was on Pravachol for 3 months and had problems w muscle aches. Also had problems w increased liver enzymes, so reduced dose from 20 to 10mg and went to every other day. Still had some side effects and was switched to ZOCOR.
Have been on zocor for 3 weeks in combination w ZETIA. Worst side effect for me is the lightheadedness (like being stumbly drunk) and malaise that others report. Some muscle pain in legs and arms (though not as bad as w Pravachol). Cannot sleep through the night, but am tired and worn out all day. Some increased level of depression, some sexual side effects. Have had pain "behind" my eyes. Some difficulty breathing.
Will be having blood work again in 1 week to see if probs still exist w liver.
Are the side effects worth the reduction in LDL? Worst part so far is that my chol has not been significantly reduced. It may be better to leave the drugs alone and concentrate on diet, excercise and try some herbal ("snake oils") remedies instead. I have an MBA in mktg and am married to a physician.. i wonder if these statin drugs are more of a well marketed product rather than a proven treatment protocol.
