Hang in there Lisa. I'm on Day 6 and all is going well. Really good sleep, very little white on the tongue, only a couple incidences of bad breath and I chalk that up to the previous fasts and eating right in between.
Initially I had planned on water for a week then a week of juice and just alternate like that until the end of the year; however, if I keep feeling like this, I will see the water through for as long as I can. I believe Steve is on Day 22 and going for a break of his 27 day record. I'd like to see how far I can go as my longest Water Fast has been 9 days.
