im not sure the chemistry here but there is a sweet spot. i use what the recipe calls for and add a little more, up to half again of the original amount.
it is a good flush and gentle. doing it 7 days in a row will produce miracles.
look at the potassium content of your food. are you getting 5 grams a day? thats extremely doubtful. potassium is just as important as salt. i double the potassium amount in IMAM to one tspn instead of a half. i also supplement 500-1000 miligrams a day of potassium. its having a very positive effect.
