That's one protocol. You don't have to use it all or you could just eat a couple of apples. After 3 years I still vary what I do. I fasted yesterday. I started this morning with 2 quart
salt water flush. (yes, I said 2 quarts). You should be clear before doing one, so I was surprised when an hour later I had a signifcant BM. Ate my flush day lunch of apples/oatmeal and orange juice. An hour and half later I am still eliminating effects from the salt water, but I'll know my flush day meal will have a clear tract. (Note: never did it this way before) Later, 4pm, I'll have a 1/2 potato with mixed steamed vegetables.
