1 month colonix, need help

I've been on colonix for about a month as of 2-3 days ago. Right after I hit a month, I started experiencing nausea, headaches, but mainly the "urge" to vomit about a few hours after I eat. I never actually vomit, I just hold it in, but I'm pretty sure I could if I tried. Bowel movements are still normal, but my stool has been a pale YELLOW for the past few days. I tried looking up what's wrong with me throughout google and the forums, but doesn't seem like there's a straight answer.

Are the toxins overwhelming me? Should I start taking Bentonite (since colonix doesn't have any toxin absorbing ingredients)? Is my liver messed up? I'm 24 if that matters. As of right now, I stopped taking Colonix altogether (I'm supposed to be in the 5-day fiber only stage). Can someone please explain what's going on? Thanks.
