Those of us who've developed a brain that can't shut down as easily as you turn off your console (probably a result of playing too much,) we know how trying to sleep can sometimes be more tiring than levelling up a healer with no mana or potions left. Well here are some suggestions from medical blog Spine Health to help you get some snooze.

• Get more daytime naps: Nap straight sometime after lunch. Just for about 20 minutes; enough to refresh you but not enough to interfere with your regular sleeping hours.
• Avoid hot baths before sleep: The body needs to cool down to sleep. A hot bath will actually wake you up. Which is not to say you should take an ice cold bath. You're a gamer, not an eskimo.
• Make your room cold: As stated before, a body needs to cool down to sleep so this would help the process along. The blog also suggests a warm comforter for added... comfort.
• Exercise!: Intense exercise releases all that extra energy and your body will just naturally fall to exhaustion.
• Avoid red wine: Drinking red wine would keep some people awake. Personally I prefer beer.
• Expose yourself to sunlight when you wake up: Yes, sunlight. It won't burn you to ash. It will reset your body clock and let it know its morning. In effect it will know when it's time to go to sleep.
• Avoid TV and Internet: Avoid them 30 minutes before you go to bed. They stimulate the brain and prevents it from toning down to sleep.
• Block out noise: Although you don't have to take Daredevil's method and sleep in a metal coffin full of water, it does help to just sleep in a quiet environment.
• Practice a sleeping habit: This would help your body know when to sleep.
• Avoid stress: So your Bioshock Big Daddy's broken. Don't sweat it, just replace it. It keeps you from tossing and turning in bed.
• Keep a pen and notebook near your bed: Sometimes we have thoughts we want to dwell on but it's keeping us awake. Write it down and tell your brain to shut up and deal with it in the morning.
