I agree. And I just hit the D, but not too bad, at the 10 drops. So I think I found my ideal upper limit at either 8 or 9 drops. That's what I'm going to stick with for now. Basing on weight, I should be higher, so I'm more going to base it on where I'm getting results. The tough decision as you do point out is whether to increase later or not once results start to slow down. My problem is that my "problems" are undiagnosed, so I don't know if they may be something more stubborn like virus. I do have an Epstein Barr like virus, and my sister has same but in her case it never goes dormant. I think what I'll do is continue until results slow down, then reduce or quit ... take the optimist's view. IF I start to revert, I'll known I should have done the opposite and should have increased. In that case I'll just start all over and try increasing when I get to that point. I've been patient this long, I can be patient longer.
EDIT: Wait a minute, maybe I've been calculating the weight dosage wrong. Is the number you come up with the dosage for the day total, or for each dosage (so the calculation result x2 if doing two doses a day)? If it's for the day total, then I am over on the weight dose, and should be at the 8 drops x2 (a tad high according to the calculation but rounding off is close enough). I used the child dosage calculation. If that's the case it is definitely a good way to decide what will be effective for your size and not get the D or V, at least in my personal experience.
