Firstly, I'd try and sort out what is stressing you out - easier said than done, I know. Also, I'd cut out alcohol for a couple of weeks. Try not to drink any caffeinated drinks after 2pm. Do loads of exercise - best remedy for a good nights sleep and if all that fails, try this relaxation technique: Breathe in for a slow count of 3 and then breathe out for a slow count of 6. Concentrate only on your breathing and counting until you are in the land of nod........sweet dreams....
