Autoimmune Diseases and Fatigue

Fatigue is probably intertwined with the definition of "illness", almost any illness, but with some conditions fatigue becomes ingrained into the afflicted person's being and is a feature of their daily life. Such is the case with the highest profile disorders, cancer and cardiovascular disease, but it is just as true with at least some autoimmune diseases. I have a long history of dealing with autoimmunity and the complaint that kept bringing me back to doctors persisting in finding out what was going on was the dogged lack of energy, vitality. I got guess after guess after guess and when I got the "answer" it was basically that fatigue was part of the deal with the autoimmune disease that I have, Sjogren's, as well as I'm sure many others. So what I'm asking here is if you experience it, fatigue, how has it impacted your life and how do you deal with it? Have you found anything that you are sure mitigates it?

In my case its exercise, rest, and a fairly regulary low dose, around 50 mgs (usual recommended dose 200 mg) of modafinil, which I don't take for Sjogren's but rather for "Excessive Daytime Sleepiness" linked to Obstructive Sleep Apnea. I accidentally found out that it mitigated my general weariness. I've read some solid studies that found that American Ginseng can help cancer-related fatigue but apparently it doesn't work for Sjogren's, for me at least. Since fatigue impacts a person's total life experience in all domains, any information that might lead to dampening or controlling it would be very helpful to a lot of folks I'm sure.
