Hmm. Not really. I say water, btw, but I also drink black tea and occasional diet cokes. The point is no calories, or virtually none.

I would suggest starting gradually. Initially I think I did 48hr fasts. After a couple of years I upped to three days. Following Longo's stuff last year I moved to five.

No supplements. Definitely no laxatives ;-)

I don't start eating again particularly slowly. But I don't binge either.

The most amazing thing to me is that I don't get hungry. I haven't eaten since Sunday night, and I feel fine.
