I myself have 5 autoimmune diseases. The theory is, if you have one you are prone to get more. I have had these problems for years but refuse to quit work and still work full time, taking off days when I can. Have been told I should think about leaving work, but I am stubborn. I been taking liquid B12 and that seemed to help for quite some time for the fatigue. In the last 4 years they have put me on Modafinil, but I got more tired with this. I am now on Ritalin and that seems to help some, so I am sticking with that for now. I as well have the sleep apnea and use CPAP. I was falling asleep on the way to work. That has helped with the driving to work issues but still am tired during the day, so this is why they are trying other medications. I have very mild sleep apnea so feel it is the autoimmune disorders causing more of the fatigue. Thanks for the article you supplied. I myself do mild exercise and Yoga which have both helped too.
