We've looked for several years now, with a primary dr's help, and arent coming up with anything. My husband has every symptom of Chronic fatigue, except that, he is very fit and doesnt get wasted after exercise. He feels better after exercise.Could this be because he also has an heart arythmyia(sp)? He is taking sertraline,provigil also. He began taking the sertraline due to no energy, and he has restless leg syn. also. He is a happy, involved husband and father.Most days he does well to get through the day, and pushes himself to do everything, even workout.Thanks for any consideration and helpful suggestions. He is a very active, capable man and it breaks my heart to see him this way.
