Someone had asked this question before, and RG's advice was to follow the dosage instructons. Too much of a good thing may become bad, cos our bodies can't cope with it. Worse, the worms will get used to the doses and become resistant, which you REALLY don't want. I suggest you stick it out on the current dosage, then wait another 90 days and do another around. This is the best and most consistent way to be completely rid of the critters without doing any harm to yourself.
