Derek Enlander, M.D., states, "If CFS patients overdo exercise or any physical activity, immediate repercussions typically occur. At times, CFS patients do have spurts of energy and typically overdo because suddenly they can do things. One of the hardest obstacles to learn with CFS is to find balance in all things. Patients walk a fine line regarding exercise and physical exertion. CFS patients have relapses that often last for several days before they recover. I tell patients to follow this rule: “only do 50% of what you think you can do."
