TV usually keeps me awake. What I usually do is splash cold water on my face to become totally awake, then try to go to sleep again. For example, the other night I went to bed at midnight and lay for an hour, not sleeping, but not totally awake. So I went, walked around, slashed water on my face, woke up totally, went back to bed, read, and fell right asleep. I can't sleep without reading first, I've done it ever since I learned to read and I can't do without it now. If all else fails, a few shots of whatever I have hidden in my closet at the moment, but that has only hapened once, and you have to be careful not to drink too much or else you will have a very rough time waking up. Just enough to make you sleepy.
