You cant fall asleep and stay asleep for more than 10 minutes at a time. this has only been happening for about a week ive had 9 hours of sleep in the past 4 days you used to be able to sleep easy all?

Continuation of question: I used to sleep easily all night just woke up a few times after a nightmare and would fall asleep easily. My ex girlfriend used to complain constantly that i would twitch and moan in my sleep... any1 know what is wrong with me ? ive got an appointment to see my dr. next week.
