I got sick.

I'm currently doing my second flush. I've flushed once and did a two week parasite cleanse using Clarkia along with zapping. This time I've neglected the parasite cleanse, but i've zapped a few times of the past weeks. I've also been drinking lots of ACV for kidney cleansing. In the middle of the night around 2-3a.m. I woke up feeling really sick, this didn't happen durring my first flush. I went to the bathroom and threw up some of the oil & grapefruit, and there was a distinctive yellow color to the liquid, kind of like the yellow color of a B complex vitamin pill, although I haven't been taking any. I'm going to start the parasite cleanse again today. Is it normal to get sick like this?
