i think u have the lot of tensions in ur mind. . If it is. . Then be cool buddy . . Problems are the important part of life and u should not take them as tension. . So if u try to sleep then keep away these tnsns frm ur mind.
Exercise through the day, and I really was going to say I usually have the TV on with the sleep timer, paid-surveys above kind of stole my thunder. For me this may sound weird but the more interesting the show is the more likely I will fall asleep to it, after a long day focusing on something like that makes me tired, I almost always fall asleep if I try to watch TV on the couch at night, so I do the same thing in bed when trying to fall asleep.
