I could use a little help here

[WilliamPitt]

I haven't been able to sleep for about two weeks. I start to drop off, and maybe actually sleep for about 20 minutes, before popping awake. Last night, for about the fifteenth day in a row, I saw the sun come up against my will. This has started to affect my stomach, which makes sleeping harder. I have tried exercise to wear myself out, and have managed to badly strain a muscle in my back.

So, to recap: No sleep since April, rotten stomach, torn up back. I've reached that insomnia point where I am psyching myself out; I got no sleep the night before last, spent yesterday writing a PDA action alert and a 30-minute speech transcript, drove two hours to do the speech, gave the speech, did a three-hour Q&A, talked to people for another hour, drove two more hours to get home, and by the time I got back here I was literally quivering with exhaustion.

But I laid awake until 6:37am (I remember looking at the clock), popped awake an 8, 9, 10 before finally giving up and getting up at 11. I can barely see straight right now, my stomach feels like it has snakes in it, my back is killing me so I can't exercise...and I know for a stone fact that I won't be able to sleep again. Tried a nap an hour or so ago. Came thiiiiiiiis close to dropping of and then popped awake.

Any ideas? I've already heard about taking mela-whatever, but that stuff gave my mother splitting headaches when she tried it. I have drastically cut back on caffiene. Any other suggestions would be appreciated. I've reached that violently, violently, violently frustrated stage of insomnia where sleep is a guaranteed impossibility, and if a routine like yesterday's (while on no sleep) can't get it done, I am at a total loss.
