I sleep on the couch. My husband not only snores and makes God-Awful noises, he never is still. He flails out his arms and legs, dumps me and the dog on the floor, and talks, sometimes LOUDLY, the whole bit. He also suffers with flatulence, although that he thinks is just amusing! It isn't, if you're in the line of fire. Or if the wind is blowing just right. In fact, it's darned offensive and insulting.
Once I've been awakened 3 or 4 times I can't go back to sleep. Sleep deprevation is awfully dangerous, if you know what I mean!
Also try to get him into a Sleep Program, he may need some professional advice. Life is too short. Good luck to you....but you need to have him get some help.
