Only a couple of days, and then not deliberately.

I'm actually fascinated by it, but I may be too much of a princess to actually do it. I have gone
as far as one hot meal a day at supper to save fuel, but I get really bloody sick of eating bars
really quick. While I can skip my coffee in the morning and stuff, I find dinnertime I want something substantial, and frankly, my non-dehydrated snacks like nuts jerky and sausage
I think weigh more than my dehydrated dinners which then will require 2/3 of an oz of alcohol
to prepare, (+ pop can stove and 3 oz pot) - so I'd really have to put it together and do the
math before I'd try it.

What's your menu like? Are you just doing bars and shakes or a little more variety?
