Gosh, never heard of that...will have to look into that.
I drink smartwater by glaceau because it has electrolytes in it.
Also now I drink a bit of vitamin water zero, just a little bit, because again it has electrolytes, but does have a few carbs (no calories but some carbs???) so just a glass here and there to have the taste of something other than my own gross tongue in my mouth.
Brush your teeth/tongue many times a day. Tasting toothpaste is better than tasting nothing.
Take some kind of laxative or other cleanse or enema or something at the start...you don't want a steak dinner from 2 weeks ago in there for 14 days....not good!
Clear your social calendar...you can't fast and socialize, IMHO.
