I was thinking the same thing as the two above. I sleep naked all of the time and I don't think it creates any extra cravings in my mind. It's comfortable and I sleep much better. In fact, when I do occasionally wear something to bed, I usually wake up with it on the floor.
I've also heard (and can confirm for myself) that it increases intimacy with your partner and encourages healthy sex. That's been my goal in all of this - to have normal, healthy sex - so my girlfriend and I sleep nude all of the time. We love the closeness of each other and it's very comfortable. And moreover, it doesn't always trigger sexual feelings for us. So I believe it's possible to be nude, be close and not be triggered.
You'll have to figure out what works for you.
