If your following Humbles protocol you probably did it right. Keep upping the dose until nausea. Then back off a little always trying to increase testing the upper limit, working your way up to 15 drops several time per day. The gold standard.
But I work and I don't have time to take it that much. I also don't want to take the chance of getting sick while doing my duties.
Actually I'm not taking it at all right now because I'm not suffering from any infection at this time.
