You will probably be able to confirm all of these things with round 2. I know we did. I have heard that some children show major regression but my son never regressed while doing the round. He tended to loose a little ground when he neared the start of the next round. Almost as if the chelation were wearing off or the mercury was being released from the cells back into the system or something like that. Now he doesn't do that so we are about to add ALA. I am a bit nervous about it because I have been told this will definitely cause regression and more stimming. Not looking forward to it at all. Keep us posted on the progress.
