Hi Muzz,
Zocor is a statin drug and side effects can include weakness and fatigue. Statins block the bodies production of coenzyme Q10, which is needed in energy production. I encourage you to discuss a coenzyme Q10 supplement with your physician. You may also be interested in the following post and I've also included a link to an article series from Dr. Lundell on statin meds.
