I was reading the thread (is that the right term?) on Cymbalta. I weaned off Prozac for a week and started Effexor, a cymbalta type drug, on Monday. I was dizzy a bit, a bit of dry mouth, and drowsy, but I noticed nothing else yet. Prozac worked fairly well, but if I can get even a bit more energy on a different anti-depressant, I'm willing to try. Anyone used Effexor for CFS? Has anyone had success with Cymbalta and decreasing chronic fatigue?
