There was a position paper that came out about a year and half ago on the use of APS, they may help you sleep short term but long term they alter the brain and sleep architecture in very bad ways so it has been passed to psychiatrists do not use APS as first line treatment for insomnia .

Doxepin as some one brought up is similar to Trazdone however it has been a very big failure as an anti depressant , but it has been studied extensively and is sedating and is a positive effect on sleep and the brain , it was repatened last year as a medication for sleep , I hate big pharma did I mention big pharma sucks OK that's out of the way , they repatened in the name... inspired by the song silent night as Silenor, however if you are independently wealthy Silenor is for you, for the rest of us( oh that's punny) just use small dose's of Doxepin . Or if you have real problems most pulmonologist have cross trained in areas of sleep medicine beyond that find one of 6000 licensed (doesn't mean they are doing patient care , lots do just research in labs) a sleep pathologist who is a Physician that is board certified in sleep disordered medicine and can look at your sleep and figure out what's going on when it shouldn't be , now go to sleep it's late and daylight savings time is just another bank without any cashiers or customer service . I hope this helps in some way .
