Vytorin and diseases

I'm a 55 yo male, that has been taking Vytorin for 6 yrs. A year ago I was diagnosed with Fybromyalgia, at a very large research hospital in St. Louis.
I entered a drug study, but after 4mos had to leave due to a neccessary surgery. I was able to find out, what the medicine was, and contimued taking it. It was Cymbalta. It provided about a 75% reduction in my symtoms, which were: Major muscle pain, throughout my body, fatique, constipation-diarrehea, memory loss(Fybro Fog), erectile dysfunction, body temp, always hot, with sweating, and just feeling tired and crappy 24/7. I accidently came across this site, about 2 wekks ago, and began reading these and other testamonials, and started thinking, maybe it's not Fibrom, but the Vytorin. So I quit taking it. My symtoms have dramatically decreased, almost by 90%. I hadn't told my Doc, so I'll be doing that this week.And run some blood tests to see what my numbers are doing. But I am convinced, Vytorin has something to do with my condition.
