Ill

If your feeling tired all the time, etc, Benard you should go to a sleep doctor. Anyway I'm no doctor but I'm guessing you have sleep apnea it is caused by not having enough oxygen when you sleep, I have it and it is a pain. I have some of the same symptoms as you (feeling tired even when sleeping 8+ hours, have trouble doing mental problems, feel physically fatigued). I went to see one and I got a machine, I'm in a love/hate relationship with it. I can't stand using it but if I don't I feel like crap all the time.

Anyway make a medical appointment with your doctor and see what he recommends.

Jam it back in, in the dark.
