Does any of the over the counter stuff - sprays etc actually work? DP has always been a another but it has got worse over the last few weeks to the point where I have had no sleep tonight at all! I am honestly at the point where I will smother him with a ducking pillow if it doesn't stop soon
I sympathise being a fellow sufferer of my DH's snoring for many years. I don't know about sprays but is it worse if lying on his back? This is going to sound weird maybe but I've taken to say "please can you turn over?" at the first sign. It works very well. I say it calmly (!) so he doesn't wake up.
If not, I think you should try get him into a sleep clinic. The trouble often is, because the are, naturally sleeping soundly, they have no idea of the extent of the problem.
