Sleep problem

[cameo]

Hi,
My 16 year old daughter is having problems sleeping at the moment.
She finds herself lying awake for hours just trying to go to sleep. This has been going on for a while now and it's really getting her down.
She doesn't seem to be overly stressed or worried at the moment, (well no more than usual!!!)
Has anyone got any ideas that might help?
A 'relaxing' bath doesn't help, as she doesn't find them relaxing.

Kalms do not work take this from a person who has great difficulty sleeping.
