Hi guys - hope your all OK

!
Just wondered if anyone had any suggestions on what could help me sleep. It's 2:30am here and I haven't slept at all so far. I've only been getting about 2-3 hours sleep for the last few weeks so it's really stressing me out now and making me miss out on a lot of my home tutoring studies ... something which I really need to do as i'm in my final year of school preparing for my big exams in May!
My Dr did give me some natural sleeping tablets about 6 weeks ago but they don't seem to be helping.
Any suggestions would be greatly appreciated!
Thanks,
Alison x
