I've read in a few places that after marrying someone, you are supposed to be able to get a better rested bonus with something called "Lover's Comfort". If you sleep "near to your spouse" this is supposed to happen. I'm wondering how exactly do you get this to happen?

I have a house (though it is the one in Whiterun and for some reason Lydia is constantly getting in and out of a chair in the house o.O), am married to Brelyna Maryon, and I have tried sleeping in the bed with her right next to me on follow, sleeping in the bed with her not set to follow (staying in the house), putting her on the bed in command mode, and sleeping in every range from 1 to 24 hours, and I still haven't gotten this Lover's Comfort thing to happen once.

Does anyone know how to trigger it? It's driving me nuts!
