"To be honest, I don't know what I'd do if this drug didn't exist. Yeah, it's certainly got its risks, but if you've got sleep onset insomnia and the trazodone, antihistamines, and everything else you've tried has failed, don't be afraid to give Sonata a try. Even the smallest dose available helps me, which is kind of surprising, considering that doxylamine and hydroxyzine both crapped out after less than a month, trazodone barely did anything, and diphenhydramine always left me drowsy the next day and had a tendency to make me oversleep, not to mention that it takes 50 to 75mg combined with melatonin to do anything. Sonata works wonders for me. Just don't take it every night, since it can get less effective if you do."
