Everybody is different, but it seems on average it takes 30 - 45 minutes to work, and up to two hours (or more) to complete.
I've never done a
SWF (Salt-Water-Flush) except while on a MC, so I'm not sure when you'd want to start eating. But I drink the lemon drink on the
Master-Cleanse as soon as the
SWF (Salt-Water-Flush) is all the way through (that is, I stop having to butt pee).
