You might not think it but you are depressed (aparently) , i had this a few years ago slept great but come the morning i just kept needing more time in bed to bring myself to get out, once i was up i was fine. Doctor gave me tablets and had a chat in my ear. I fucked the tablets away as i didnt want to go down that route but it seemed to just fade out. Now i set my alarm a 6.55am and get up after a nine minite snooze no bother..
