why are long fasts recommended to be supervised? is it more for people who have a bad diet beforehand? what exactly needs to be supervised?? id love to do a 40 day water fast but the idea scares me, my longest fast was 3 days, nowadays i havnt gotten past one day, i just feel so hungry but i know its a mind over matter thing. how many days does it take for the "im so f**king hungry' stage to subside somewhat? also im someone who feels ungrounded very easily and dont like feeling so edgy and irritable, does that subside too?
