An alternative approach may be hypnosis for the snoring "victim". That means that the partner of the snorer is "programmed" not to hear the snoring consciously. Some even go as far as to suggest that they actually find it soothing...
My husband uses Snoreeze Throat Spray and I use earplugs. The two combined seem to do the trick unless he's had a heavy session at the pub! All the best to you and I hope you find something that works for you both ......xx
I shall be looking into some of these as I've got to go in to hospital soon and the last time I was in the whole ward moaned about my snoring. Not sure there's anything I can do though. After 3 operations on my nose I am not going to go through that again for anybody.
