Snoring

Definitely separate rooms......sleep is so important and, once you've got over the 'he won't love me if I don't sleep with him' you'll find that, actually, you love each other more because one of you has not been awake and contemplating murder several times during the night.

Weirdly I do always sleep on my side, but still snore very loudly.

Bluebellgran look on some shooting sites. My OH has some very expensive ones which are individually made. You can get cheaper ones without electronics (they cut out the gun noise but allow you to hear conversations).
