I've not found very much luck with OTC sleep aids that contain sedating antihistamines, such as diphenhydramine, because they tend to make me paranoid, and as such are not condusive to sleep. I've looked at soma before, but I'm not so sure that a skelatal muscle relaxer would be very sleep inducing (of course, that's comming from a person who's tried an atypical antipsychotic for sleep).
