I know the feeling! I had a severe infection after my son was born by C-Section (they forget to give me antibiotics) and they wouldn't let me eat by mouth but I had an IV which sure didn't keep my mouth moist. I can still remember those ice chips they would let me have. Even hospital food tasted great when I could finally eat including lime jello which I normally hate! Obviously these people saying how easy it is have no idea -- I say let them go without food and water for a few days and see how they feel about it then.
if you've ever had a root canal or any dental procedure, just think about how dry your lips and mouth get with the retractor inside. Imagine that happening to your entire body coupled with severe hunger. A gentle way to die? Give me a break.
As soon as he (and the younger two) was born, the first thing I asked for was FOOD.
