Both my physical therapist and my low level laser chiropractor (and I!) were a bit disappointed in my slow recovery from a car accident and CFS. Then I went to FFC - had an "energy shot" and did better with both the chiro and the pt, had another shot plus al their supplements and am doing even better. My pt suspected something I was taking was depleting me of one or more necessary aminos. Guess what?! The tylenol in Vicodin can severely deplete cellular glutathione levels! Could Vicodin be a major contributor to my CFS? Don't iknow, but at my Monday appointment with my MD am going to request something (or nothiing?)without tylenol. Just a thought!
