The herb valerian can help sometimes ( in tablets at the chemist or health food shops) and don't overlook the old favourite, a cup of warm milk! Agree that sleeping tablets aren't the best solution but an occasional mild sedative like Temaze may help if you are getting really frazzled. While the sleep gurus say bed is for sleep or sex, and you shouldn't do anything else there, I too find some distracting activity helps. Sudoku or crosswords are my cure! Do them till my eyelids drop then switch off the light fast! Good luck.
