Help me sleeeeep

Okay, guys, once again I need your help. I have been rather insomniacal of late and I am in desperate need of some sleep. I spoke to my doctor yesterday, who said it was common to be like this for the first few weeks of my meds increase, but if it was still a problem in a fortnight, she would look into prescribing me something. I don't want sleeping tablets (idea of being put to sleep scares me) and two weeks is a long time to go without decent sleep. Do you have any tips/genuine working ways of getting a good night's sleep? Please share!!
