It's sounds like your body clock is out of balance, but it might be challenging to get you back on track. Sleeping pills can be habit forming but I understand why people take them because not sleeping is horrible. I respond adversely to anesthetic and I usually end up not sleeping for 2-3 days.

I think you should get one of those light boxes- the trick is to expose your eyes to light and this triggers something in the brain. Can you take melatonin? If you drink caffeine products, slowly cut down. Go to bed and wake up at the same time everyday. Make sure your room is dark and quiet. Don't do things that occupy your brain - like tv, video games or computer. Learn how to put your worries on a shelf - my favorite trick is imagining I'm putting them in a box, locking it and putting it high on a shelf- this symbolizes you're done worrying.

We have those Nintendo DS's and there's this one game called Brain Age and one of the games on it, is called 'Virus Busters'. This is the only exception for games - anyway I lay in bed and play this to de-stress - it has this gentle lullaby music and it so incredibly relaxing. You can't think of anything else, when you're playing this game lol. Many times I found I actually dozed off for a second, with the game on my chest lol.

You can also try things like a warm bath and slow deep breathing exercises, where you relax all your body until you're limp, like a wet noodle lol. If you want to try the Melatonin, make sure you ask your doctor first. I think your body clock is out of balance and I hope you get it back on track. What are you going to study? Good luck Amanda
