I do not think that either of those therapies would help much. In chronic fatigue syndrome, your immune syndrome is under attack and is having an increasingly hard time fighting back. What you have to do is find the attacker - and kill it. Also, your immune system needs support during this period, so it can support you and come back. Taking care of yourself is #1 on the list, including diet, exercise, sleep, relaxation, appropriate supplements, etc. It's hard work but well worth it.
I have chronic fatigue syndrome, and my attackers were candida and amoebas. Now that I have killed them off, my immune system is coming back slowly but surely with the help of the supplements I take at the direction of my immunologist. But the question is, what is the attacker in your body? What are your symtoms?
