I have horrible insomnia as well...no matter how tired I am. The only way I can get some decent sleep is with a sleep med, and I don't want to get dependent on them. Part of mine is hormonal as well.

For me, Wellbutrin is the worst sleep-stealer. Depakote has a mildly sedating effect. Zoloft seems to neither help no hinder sleep.

Speaking of which, I need to get a nap before work.
