at day 22 I started to feel bothered by the way i seemed to have a permanent worried expression. not so much the 'look' of that as the feel. As well, I began to have to spit out a lot of salty saliva. This carried on for about three or four days, and made me 'feel sick'. (as in "sick and tired")
Looking back now, i wish I'd let it run its course. I sort of did, but then didn't wait for the return of "genuine hunger",
as a result, on re-feeding, I had a metallic taste for at least a week. i'm sure that week would have been better spent fasting-- probably to 40 days.
it was my first Water Fast though. so, i try to view it as a success.
