I wish I would have heard about not chelating while the amalgams were still in a little earlier. I was taking Chlorella and Cilantro 3x a day for a few weeks and began feeling horrilbe every morning. I felt very nervous and had like a hung over feeling (but without nausia). I think they call it brain fog. It is a very acurate description! I stopped taking the supplements and felt better the next week. I told my doctor about this and he said that my dosage was probably too low but I'm holding off on anymore chelating until all of the amalgams are out. I've had two procedures done and have two more to go. They'll all be out by the end of the month. Then he's going to put me on DPMS for a while then switch to DMSA. I'll also get back on the chlorella/cilantro and any other chelating supplement I can get my hands on. From what I've read, mercury mostly stores itself in your brain and interferes with serotonin production. Most believe low serotonin levels are the cause of OCD (which is why the prescribe SSRIs to make serotonin more available in the synaptic cleft. My hope is that once the mercury is purged from my brain my serotonin levels will increase and my OCD will diminish or go away completely. I'm just hypothesising but all I can do is see how I feel after the amalgams are out and I've chelated for a while. i'll have to wait a while to make sure its not a placebo effect.
