I'm still tired of it.
Aha! I see what you did there.
Insomnia sucks! Have you talked to anyone about it, like a doctor or a psychiatrist or something? I'm not either of those things (obviously) but I've been an insomniac for about two-ish years and there are as many strategies for dealing with it as there are causes, so sometimes it's good to chat with someone who can help you figure out what you should be doing.
Besides the usual(-ish) ways of knocking yourself out (sleeping pills, neocitran, a bottle of red wine, etc), there are often more specific things you can do that may not put you to sleep, but that will definitely help make the environment you're in better. Like, my neighbourhood is super noisy and the walls in my house are really thin, so I got a white noise machine and now I don't have to listen to everything going on around me. It seems obvious, but sometimes these sorts of things are easy to overlook. Exercising in the evening is good too-even just going for a short walk will tire you out a little.
One of the best tips I ever got was that if you wake up and can't get back to sleep, you need to get out of bed. Your brain and your body remember what you use your bed for, and if you do stuff like reading or writing or watching t.v. or what have you, your brain won't be trained to think of your bed as only a place for sleeping. This especially applies if you're lying in bed worrying about getting back to sleep. Get up and walk around, go downstairs and watch t.v., read sitting on the floor, but don't stay in bed. It might sound kind of silly but, I don't know, it helped me.
Anyway. Maybe you know all this already and I have managed to bore everyone to tears with my Handy Hints For Sleeping. Point is, insomnia is no fun and I hope it leaves you alone.
