I was starved (not dehydrated) for 4 days once while in the hospital. I was so hungry, every time I saw a nurse I begged for food. These "experts" who are saying how "peaceful" death by starvation/dehydration is should try it sometime.
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.
