I don't know if I have, or had Asperger's Syndrome, but I do have Celiac disease - and have benefited from a gluten free diet. This diet is also recommended for children and adults with Asperger's Syndrome, Autism, ADHD, and many other conditions.

The GF diet did clear up my head, resolved many other problems, and I have no pressing need to smoke anything now. I am much more selective about what, and how much, stuff I use. Right now, it's practically nothing. Years ago, I did it a lot more.

If you haven't tired this diet, I'd encourage you to do so. It can't hurt, and may be the solution - or a big part of it.
