The last few days ive not been able to sleep properly and its begining to bug the hell out of me

For instance, this evening i went to bed around midnight and three hours later, im wide awake again

Usually when my head hits the pillow im out like a light but just recently it seems that im staying up later and later and its becoming ocunter productive.

Anyone have any tips for actually getting a good nights sleep that doesnt involve sleeping pills?

Regards,

Lee
