chronic fatigue syndrome
"I have had 4 back surgeries ( pins, screws, plates, etc.) and both of my hips replaced, all before turning 43.  Before this, I earned a Ph.D., became a Prof. in Accounting was rewarded multitudes of student-awarded, colleague-awarded, and superiors-rewarded accollades.  Then, with all the narcotics, opiods, hospitalizations, etc, tenure was literally jerked from my grasp, and I have been forced out of three other universities since.  The depression of repeated recoveries from surgery and then med withdrawals and job losses drove me into extreme depression. Got the pain under control but it got to where I was in bed 6 of 7 days full-time. I was taking Cymbalta, but when my Dr. tried Nuvigil, it brought me back to the happiness I had known before."
