i don't know much about it hon but I do know there are natural ways to help relieve similar kinds of things. have a read of the naturalnews website. sounds bonkers but exercise particularly helps relieve depression so if your fatigue is linked to depression that might help - because it releases adrenalin and natural seratonins.

Also, this website gives you lists of foods to boost your immune system and energy. I've been having a rough time recently and I've been taking a combi natural remedy containing 5HTP which again works on releasing natural chemicals.

have a read of their website and search your conditions. Always better to try natural first, especially if you are reluctant to go on antidepressants.
