Slightest amount of noise and sound can cause brain to not think it's night time yet / not time to sleep. The suggestion for doing a crossword puzzle is good, thogh crossword puzzles aren't all that brain activating if you don't have a big vocabulary, just end up being frustrating. One thing to keep in mind, you can't 'stop' yourself from thinking, but you can change what you're thinking about... meditation is basically exactly that as well..
