How can I kick this freaking insomnia?

I’m currently on two SSRI medications, one for 2 months and one for 2 weeks. I’ve been having more and more trouble sleeping.

-I’ve tried 100mg (twice the recommended dose) of doxycycline hydrochloride and it didn’t really do anything.

-I’ve tried 5mg, then 10mg, then 15mg of Ambien. 5 and 10 did not work. 15 worked great and I had the best sleep I’ve had in a long time, but my doctor says that’s too high and won’t prescribe it.

-I’ve tried 9mg of melatonin supplements. Didn’t do anything.

-I think tea tastes like dirt and despise it, so chamomile tea isn’t really an option, and frankly, I don’t think it’s going to help me if drugs and natural supplements didn’t work.

-Reading didn’t help. Nor did watching The Joy of Painting, if you can believe that. Laying in the dark didn’t help (I’ve slept with the TV on since I was 10)

On a more drastic attempt, 1000mg of vicodin didn’t help. I took two of my roommate’s percocet, I don’t know the dose, and that was freaking fantastic… but I liked the high so much I didn’t want to sleep, I just wanted to be high, and I knew for damn sure I was going to get addicted to them if I kept it up.

The doctor wants me to try Lunesta, but I am obviously hesitant to pay for yet another medication that won’t do anything.

I don’t suppose anyone has any suggestions? My doctor isn’t in until Monday and I would sort of like to sleep before then, when I can call him.
