I have Chronic Fatigue Syndrome or Fibromyalgia. Every Doctor references it differently.?

I was wondering if anyone has a doctor out there that has found a successful treatment for this condition. I am on Pain killers, sleep meds and xanax. And also expected to excersize everyday. How do you excersize when you have no eneregy to move throughout the day. I have also had vitiman B12 shots with no help.
Does anyones doctor seem to have a reason for this condition. I am wondering if it has something to do with hormon balances as almost everyone I know that has it has had a hysterectomy or gone through the change. Anyones input would be greatlly appriciated.
