I put this in the medicine category because I think the nature of my problem is not trivial. Anyway, throughout my whole life I have had a tremendous difficulty waking up in the morning or waking up in general for that matter. After about 7-8 hours, I will rise from my slumber only to be consumed my immense exhaustion within 2 minutes. I end up sleeping in another 2-3 hours. In addition, if I get even 30 minutes less than a full 8 hours I cannot function for the rest of the day. I am thinking about going to my GP, but I have no idea what they are going to do. Does anyone have any ideas what may cause someone to have trouble waking up besides staying up late drinking/partying.
