> Do you just sleep in a dark room until you wake up?

Yes. Although I have no trouble sleeping even if the room isn't dark. Falling asleep is usually a little harder if it's not dark, but once I'm asleep the light doesn't wake me up, unless it's really bright (like sun shining directly through the fully open window).

Maybe light alarm would awake me, not sure how bright they are.
