Hello Michael

as you mentioned you were dx with Tourette Syndrome, here is the link to that forum http://neurotalk.psychcentral.com/forum25.html

There is a very good website that deals with natural approaches to tics and Tourette etc at www.latitudes.org as well as their book

My son is a young adult now and has been dx with TS since pre teen years. Modification to his diet, environment and the addition of specific supplements made a huge difference for him, as did acupuncture. I have an old thread on the TS forum about what helped him.

Mountain dew is so very unhealthy and for people with neurological conditions, things like the yellow 5 dye in it (tartrazine) can be a trigger

It's good that you have educated yourself on so much and are taking charge of your health.
