I take trazodone at bedtime for insomnia, and it works like a charm. I haven't noticed any side effects, aside from sleepiness, which is the desired effect for me. When I was on any of the benzo's (zoplicone, oxazepam, etc.) for insomnia, I noticed the unwanted side effect of memory impairment. I don't get this side effect from trazodone.
I checked several sites online, and snoring was not listed as a side effect on any site. You might want to google "snoring, causes" and see what comes up.
