Can't sleep. What to do?

I got tired at 9:45 last night. I was lying around in bed until 1 AM, when I had way too much energy and started walking around. For about 45 minutes -I think- I've been online. Previously I tried meditation, reading, listening to relaxing music, changing the temperature of my room, putting socks on, taking them off, just lying there, and trying to convince myself I absolutely had to stay awake because that used to work, a hot shower -taking a bath requires removing the spiders from the tub, they run when the shower water starts-, about a quart of chamomile tea, and visualizing first sleep, then general relaxing stuff. No luck.

Meaning I've been up for about eight hours, tired as all hell but unable to sleep. I don't think its dietary, the only sugar I had today was some ice cream at about 4:30 and canteloupe for breakfast.

I've got to stay up today but I know that tomorrow I'm still going to have trouble. What can I do, if medicine is unavailable?

I'm not on any meds.

I usually have a lot of trouble falling asleep and then when I do, I wake up a lot during the night and always just feel tired.

I'm 15.

first, get offline. especially get out of Y!A. anything that puts questions into your mind while you're trying to sleep is definitely NOT going to help. next, go drink some warm milk. heat up a glass for about 30-45 seconds in the microwave. i know it sounds gross, but it's not bad, and it contains tryptophan (spelling?), which is activated when the milk is heated up, and will help you sleep. when you lie down again, try ''seca tunda,'' an old chinese breathing exercize. breathe in deep and fill your lungs, from the bottom to the top, slowly. count five seconds out (in your head) while you hold it, and let out the air, from the top of your lungs, to the bottom. count out five seconds, and repeat. you should only do this for five or ten minutes the first few times. also, it helps to imagine a glass of water being filled up and emptied the first few times you do this. that way, you can visualize the exercize, in a way. what you're actually doing when you practice seca tunda is retraining yourself to breathe. if you do this every night, you'll soon start to notice that you're doing it naturally, without any effort. breathing this way maximizes the oxygen you'll take into your blood, and thus makes for more efficient sleep at night (and also helps to relieve tension by clearing your mind), and more energy during the day. i hope this helps.

Don't go to bed so early.

I eat ice cream, listen to a Moody Blues CD, and then in bed I gently repeat the name of Jesus. I ignore other thoughts and rest in the knowledge of Jesus love and protection.

Just lie in bed, with you're eyes shut and think of something... anything. Planning you're next day, you're fave tv show... and do it long enough you're mind shuts off and you fall asleep... Works for me.
