Before taking sleeping aids, select a bedtime and stick with it. Never change it unless you make a permanent change. Also, establish a bedtime routine (a series of tasks) that begin perhaps 1/2 hour to an hour before your bedtime. Choose specific tasks that you know will relax you in preparation for bedtime. These tasks could involve consuming specific foods or drinks that help you relax. Also, they could be activities such as watching tv, a movie, playing a game, reading a book, etc...
