One night, I was so frustrated, I recorded his snoring on my phone and played it back, full volume, the next day. It didnt stop the snoring, but it has meant he is now far more sympathetic/embarrassed when I moan!
I have also tried altering my own mindset. Crazy though it sounds, I have almost learnt to like the sound of his snoring. I try to see it as something reassuring - 'I have a lovely partner and he's healthy and alive'. I then try to get in tune with the snores, breathing at his (much slower and more relaxed) pace along with him as he sleeps. On several occasions, I've then just nodded off!
Cant believe I have admitted this as it sounds crazy, but it has really helped. I no longer get the anger and the 'help, I will be so tired tomorrow!' feeling
