A few times now I have done moderate dosing, first a very few dots to get a little of the feel. Just enough to get the feeling of warmth, dizziness and tingling in the limbs. Then, usually within a half hour after that, I increased the dose to just below the treshold of vomiting. This way I could do it with a week or so in between. Moderating it like this was a little uneasy, why would I not go for the full purge? Inside a voice says, purge it all and purge it hard. But that is just too much very often.
I read a bit about the black bile thing. Hasn't happened to me, thusfar, though I saw a guy once purge for 2 hours straight and he had black bile coming out.
Right now I want to do a full purge and with a special application in mind. Every morning I spend a time feeling if it is the right time and thusfar each time it was a no go. This can go on for days, even weeks, but eventually I either cut the dilemma or the feeling comes and I do it. Anyway, the harshness of full purging caused my body to be very cautious and give clear signals whether it's okay or not...
