Look I know this has nothing to do with your problem, but just thought it was a little something to make those snorers out there happy.
A friend of mine suffers a lot because her DH is a chonic snorer! He keeps on telling everyone that he cant work out why she wont listen to him when he says that he really isnt snoring, its just a mating call lol......
I had to laugh about that one, but I do know how people feel when their partner is a snorer, the father of my first four children was a chronic snorer and I was forever jabbing him in the ribs to shut him up!!!
I would say if your snoring is so bad and upsetting DH, then yes spend the nights apart, its hopefully only a pregnancy thing, or perhaps look into getting the strips that others have mentioned, it really is a bad thing to have to put up with the horrific sound of a snorer lol. I must be a very lucky woman cause my DP doesnt snore, even after a good night out lol.
