You have to pick:

I suppose it depends on what the contents is...

Whiskey for my man, and beer for my horses, I say!

Sh*t, this is already true.

this is invalid, Whiskey tastes unbearably disgusting already so just ALL liquids taste disgusting.

@talbot15: The option states that whiskey doesn't taste disgusting, so that'd change.

Is there enough water in whiskey to live off without getting drunk?

If not, I guess I could eat foods with high water content.

Bryan mentioned to me that drinking only whiskey would kill you. Not only does it not contain enough water but alcohol dehydrates you.

I could still possibly live on jello though.

If the contents are just air, hell yeah!

I think the intent is the contents of a used diaper. But perhaps it is better if the contents are unknown at the time of the choice. Maybe it is indeed empty. Or maybe not. Once you agree, you're committed.

The option doesn't say you can't drink other things, just that it tastes bad.

I'd just force myself to drink water a couple of times a day. It's like medicine.
