I am a 40-something male with chronic fatigue. My 76-year old father sleeps 20 hours per day, and my 11-year old son is also exhibiting unusual fatigue. Doctors have been unable to help. Blood tests have revealed nothing unusual. Out of desperation, I’ve begun to track every conceivable factor in energy production and fatigue that I can find and experiment with them. I am new to QS and eagerly looking forward to learning from the community.
