I tend to shower at night. I usually exercise late in the day, so obviously a shower after that before going to bed is a must. That and that I'm not a morning person, I'd much rather spend the extra time laying in bed than actually having to do something.
Lastly, I'm not sure what all this talk about sweating in your sleep is. Unless it's exceedingly warm I don't sweat in my sleep, or more so, haven't noticed sweating in my sleep. Though I do prefer to sleep in the cold under a decent comforter. It's quite easy to keep cool then as you can just stick a foot or your leg out from under the covers.
