This works, try it.

Turn everything off, TV, radio, all your lights etc. Even you cell, sometimes we put our phones on vibrate at night, so as not to be disturbed in our sleep by the ringing. But when you do that, your mind still knows it's on, and remains at a state of readiness anticipating it to ring. So turn it off.

Try to make sure your room is as dark as possible, if you have a computer that has a light on it, cover it with something. Make your room really dark, the darker the better. This helps regulate your body's production of seratonin, and you need seratonin to sleep. It's what makes you sleepy, it regulates your biological clock. (What makes you sleepy at night, and active during the day).

Lay in bed, cool sheets if possible. Not cold, but a cool environment helps your body to relax. Even in the winter, a really warm room can make for an uncomfortable night's sleep.

Start off on your back, with your face facing the ceiling. Raise your right hand (left hand if you're a southpaw) and slap the shit out of yourself. Slap yourself until you fall asleep. The first 20 to 30 slaps hurt, but after that your whole head becomes numb, which makes this process a lot easier. Just continue to slap your dumbass self until you pass out. My hands are kinda big, I'll slap the shit out of you if you need. I charge though, not necessarily money, I usually just clean your house out after you fall asleep. PM me for detail.
