I completely understand with needing to hear from others. We tried so many supplements over the years. We also did neurofeedback (muscle testing) and cognitive behaviour therapy with a child psychologist. Looking back the most important things that helped were - clean diet (real food not processed) with low oxalate foods, tonsil and adenoid removal, and learning how to "fight" his ocd and "worry brain" with common sense techniques that were given to us by the psychologist. Those techniques continue to be useful to this day, but only when he's not in a flare. When in flare it's too hard - his brain is inflammed and only abx will work. Tamar Chansky's books are helpful in understanding the talk-back techniques. I would also say that learning to re-wire his brain with music lessons also helped. People seem to look at me sideways when I say that but I truly believe it made and continues to make a difference. Another book I recommend is: The Brain's Way of Changing by Norman Doidge. It's been a long journey for us and we understand that our son will always have tics and worry brain issues to some degree, but they can be managed and he is living a great life. He excels at school, has many friends, participates in sports, camps, etc and is very happy about his life.
