For the past few months I've been feeling tired and having a lack of energy unless I doze off an hour or two after work. After that I'm all good again, and if I manage to stay awake those few hours after work I feel better too, but that takes alot of effort. I didn't mind it at first it was nice napping but now it's turned into almost every single day and it's becoming an annoying "need" and I think I'm programming my body to keep doing this. I've tried changing my sleep rutine and the less I sleep the better it seems to be. 5 or 6 hours seem to be the best, if I sleep less or longer then that I feel too tired to do anything. Exercise doesn't help, if anything it makes me more tired. I'm not sure if it's from work stress or what but I've been wondering for awhile if it could be some sort of disease cause I've never felt tired like this all the time before.
