Obviously this could go in some very strange directions. I added a few humorous options. I've omitted a few as well. For example:

Night sweats: Sometimes you wake up and your bedroll is drenched.

Not an option. But feel free to write-in any votes for interesting ideas that may or may not have any practical use in Skyrim.

However, keep in mind that this poll is actually meant to provide useful feedback to Bethesda. I'd really like sleep to have a more important role than just positive effects like those in Oblivion and Fallout 3.

YES, this has been discussed a billion times before. NO, I don't care. NO, I don't care that Bethesda doesn't care. NO, I don't care that you don't care.

Thanks

EDIT: Added "Don't care. / Stupid question." as an option for all questions so that poll may be submitted by those that only want to answer partially. Sorry, I'm new to this poll-creation stuff.
EDIT: Fixed some grammatical errors.

Poll was too specific at parts, couldn't be bothered to do it.

I just posted on sleeping, healing, and nutrition here:

It should feel natural, what you'd expect from it. Didn't vote, just too weird and specific for me, and some options are too far fetched.

Sorry, I didn't realize that some questions aren't optional. I've added "Don't care. / Stupid question." as an option for all questions now.

As for some options being too specific, you don't have to choose them

Hopefully it will be similar to Real Sleep Extended (Oblivion mod) and New Vegas hardcoe mode.

If you don't sleep (or eat and drink) on a regular basis, your sleep deprivation level (or starvation/dehydration) goes up, your attributes, skills, HP, carry weight capacity drops, and eventually you die.

as long as it's optional (not sleeping to level up though) that sleeping affects stats i'm all for it
