Cazz - sorry to hear you're not sleeping. I've got a few more suggestions: Are you exercising just before bed time? probably too knackered huh. Exercise is supposed to make you sleep better but not if you do it just before you go to bed. I used to try to get into DH's breathing pattern when he is asleep - slow deep breathing, not the snoring. I also use chamomile tea - 2 bags with some honey.
Hope that helps!
