hello. I believe I am suffering from chronic fatigue. I have bouts of extreme fatigue and am unable to function for days. I am very tired, achy, groggy, emotional and it usually last a few days and gradually lifts. then I am ok for a few days/weeks and it hits me again. I require a lot of sleep at night and that is hard to do because i cant stay asleep and its hard to fall asleep. when I do feel good it is a real good energy but when it hits me it is all I can do to get thru the days. any insight would be greatly appreciated.
