Eveytime i fall asleep, i usually wake up 5 minutes later because i feel as i blackout and my eyes roll to the back of my head. my head now hurts.?

Sleep disorder: You may be experiencing episodic sleep apnea, but i would wonder if there is some seizure activity. Do believe you should see a sleep specialist and undergo an overnight sleep study. If indeed you have sleep apnea, and a clue might be snoring, you could benefit from a c-pap unit. Get all of this evaluated, you will be far more satisfied.
