My husband and I just finished our 30 days on the dewormer. We both stayed with the dosage of 1 tablespoon, twice daily. My husband is 6'0 and 195 pounds and this dosage had him expel many white worms on two occasions. I am reading MH's booklet now and it says you can adjust the dosage based on your weight.. It says you can take one TEASPOON per each 50 pounds of weight - so you might want to take three teaspoons, twice daily. Or you could just try the 1 tablespoon, twice daily and see how that works. It is up to you.
I also ordered two bottles of the dewormer. That lasted my husband and I the entire 30 days. So even if you upped your dosage based on the above, the two bottles should still last you the entire 30 days.
