Hi. Welcome to the bulletin board and the cleanse .
Congratulations on doing something good for your body .
Yes, doing the salt water flush after eating is the wrong thing :-[. Please reread the directions on the cleanse on pages 17, 18, 20 - 22. The salt water flush should be done first thing in the morning after an herbal laxative tea the night before. [By the way, it's a quart of salt water (32 oz.), not a pint (16 oz.).]
If you want a short summary, see "The Master Cleanse" page by clicking the Site Home link at the top of the page. THIS IS NOT A SUBSTITUTE FOR THE BOOK. For instance, how to break the fast is covered at much more length in the book.
I hope this helps you get all the possible benefits from the cleanse.
