My husband is currently working out of state every two weeks for two weeks. I get very used to having the whole bed to myself (and since it's been my bed since high school, I think I relapse into thinking of it as my bed and of course I"ll sleep dead center, spread in all different directions, or diagonally across it...). And then he comes home, and it definitely throws me off a little. He makes the bed a lot warmer, and I like it to be freezing when I sleep. But I've found that since I started having a strict bed time with a regular routine beforehand, it helps the transition when he's home. I think my body gets so used to the idea that I"m supposed to be in bed, lights out by a certain time, whether or not he's there, that it just... goes to sleep, even if he is there. I don't know if that's something possible for you to do or if it's something you're already doing and still having trouble.

What about getting a bigger bed...? Is that possible, or do you think it would help?
