Vytorin and tiredness

Have been taking Vytorin for about two months. So far, main side effects have been frequent stools, gas, and occasional diarrhea. Some tiredness; hard to know if it's caused by the Vytorin, though.

The only truly bad problems I've experienced happened when I ate a half a grapefruit. That night I awoke with a splitting headache and chills/sweats. The next day I had to take Pepto Bismol before leaving the house because I was constantly in the bathroom. Obviously the grapefruit doubled the effect of the medication.

Ezetimbe, and Zocor: I have a lot of the same problems, muscle soreness, head aches, swollen hands, restless nights not sleeping very much and no sexual drive at all. As well I now have a blocked artiry, and a valve that is not closeing.
I believe this was caused by the Zocor witch caused long and short term memory loss, short temperedness, tiredness all the time (with out doing anything to cause this problem) as well as muscle pain all over my body. I am a man about 64 years old with no heart problems before this. I worry that the Zocor has effected the heart muscle, and has caused the problems with the valve not closeing. If you have had problems with either medication please let me know, also tell your doctor and keep telling them if they don't listen change doctors.
