I have suffered from diagnosed Chronic Fatigue Syndrome since the accident. Incidence will vary amongst individuals. I currently wake up with full-on fatigue, and must lie quietly in bed, or try to go back to sleep, until the session terminates. This rarely happens before mid afternoon (today I was bedridden until 6 pm).

I have all the symptoms you describe, the fatigue, the nausea, dizziness, weakness.

My CFS used to be much worse. What could be worse? The fact that it never terminated at all. 24/7 lasting for years.
