as long as you're eliminating 3-4 times a day then you can get around the SWF. Remember, the book indicates that if you can't do the tea 2x a day then you should do the SWF (Salt-Water-Flush) in the morning.
I tried the flush and it made me feel horrible. That's not what this is about -- we shouldn't have to do this cleanse and feel completely miserable at the same time (if using tea) works better.
