I'm just wondering if I'm the only one having doubts around here?? I've been sick for 4 years, diagnosed (through elimination) with cfs for 2 years but still grappling with the horns of this monster! I'm happy with my meds and my diet and my sleeping.......so don't feel any of them to be the culprit of my fatigue. However, I've had heart arrythmia for the 4 years..........as well as exhaustion after exertion. So my dilemma here is which came first...........and what's currently causing my fatigue ? Anyone else in this rocking boat?
