I thank you all for your responses. It is so encouraging to hear from people who share in this experience. I guess I will go and research what an environmental doctor is. I will also keep reading on this site. Thank you for the tip on the "essential threads". I will start there. I am keeping a food journal which has been very enlightening. The reason I removed vinegar is that I have read quite a bit about the candida diet. My son loves pickles, olives, and aged cheeses and I wondered if they could be a trigger for him. After just 5 or 6 days of diet change, the results were amazing. But like I said, his tics are back and now I am just trying to see which foods really do make a difference. Joshua's tics are mainly facial, and he also sniffs and coughs. He shakes his head, his eyes roll back in his head, he opens his mouth very wide, and occasionally talks in a strange voice.
I'm gonna get to my reading! Thank you again for being here,
Peggy
