So here lately, I've been overly tired during the day and unable to sleep at night. When I can sleep at night its after 2am. But when I wake up, I don't remember going to sleep, and I don't feel like my normal self. Almost like my brain activity is low. My whole body feels weird when I wake up too. I'm always tired and I'm concerned there is something deeper going on. Any advice? And I'll try to answer your questions the best I can. I don't know what is going on.
