How do you tell the difference between a drug reaction and Herx?
Now isn't that the million $ question.
For me if you feel awful, then it clears and afterwards you feel better than before, it was a herx.
How do you know at the time, to be sure, I'd love that answer.
The way I see it whether my body is mobilsing toxins, killing microbes etc from within, or whether I'm taking drugs, herbs or other supplements or foods that my body perceives as toxin, it's still toxins so the effect to me is very similar... perhaps almost indistinguishable?
I'm like you Andreamarie, I react very quickly, and for me as long as I cut back treatment it clears quickly.
Then I look at what I've taken, try to work out if there's any relationship with things that were either herx inducing or toxic/non-ideal for me previously... of course I should've done this before, but somehow crucial information often hides until there's a mini crisis.... and depending on how that analysis goes once I'm feeling strongly I might very gently and gradually try and add back the supplement.
If very slow titring up over 4-7 days brings the same result, I discard it... perhaps save for some future time when I hope I'll feel more robust.
Some people can push through a herx, becuase they are sure it's a herx and are resilinet enough to do that. Personally I react to many, many things and have injured myself thinking something was a herx when it wasn't.
