HELP Am I doing the right thing?

I just completed Dr. Clark's gall flush successfully. I passed about 200 stones, among them some 100 or so green ones. Since this was my first one, I plan on doing another one in two weeks. Aside from the awful taste, I felt really good. Two days later, I ate a fairly greasy Mexican meal. I really shouldn't have but I did. That night I was sick to my stomach and vomited three times. I normally eat low fat (I am not overweight). In fact my doctor told me I needed to gain weight. I started noticing a small pain at the bottom of my right shoulder blade. Is it my guess that these pains is, at Dr. Clark said, the old stones moving forward awaiting their next cleanse? Anyway, I don't know why I did this other than eating the fattening meal. Any response would be greatly appreciated.
