I've always been a bit of a snorer but more gentle snuffles than full-blown snoring until recently when it's got noticeable worse. I'm sometimes waking myself up (usually when I'm drifting off so not heavily asleep) and poor dh is really having trouble sleeping so ends up nudging or moving me which wakes me too. I went away with friends over NY and one was very unhappy in the morning about her lack of sleep which was both embarrassing and hurtful.
Any ideas why it will have got worse all of a sudden and what I can do to help myself? I'm waking up very dry-mouthed so clearly sleeping with my mouth open and often feeling a little congested particularly first thing. Bizarrely I gave up smoking just before Christmas (not heavy but regular 3 or 4 a day) and I swear it's got worse not better! I have put on a bit of weight these past few months but I can't believe an extra 8-10kg can affect snoring that much 
Any remedies or suggestions gratefully received before dh decamps to the sofa for good
