<p>go see a sleep doctor. sound like you have sleep apnea. you could keep waking up in the middle of the night and not knowing it over and over again.</p>
<p>its not incredibly uncommon for someone with sleep apnea to wake up 15 times over the course of one night and not even notice/remember it the following day!!</p>
<p>sleeptime should be recharge time!!! if its not doing that then you need to see a doctor!! a sleep doctor!</p>
