You say that you got your fillings out, but you don't say what you've been doing to chelate. What have you been using?
As for your "crash" symptom, I know exactly what you mean. I had the same experience when I was still very sick. When I got hungry everything would go haywire, including my attitude toward others. Nowadays, though, I can skip a meal (or two!) no problem. Of course I will be hungry, but it's not debilitating like it was when I was sick.
