Tics commonly, commonly come from a mangesium deficiency.
Magnesium has also shown helpful for anxiety, OCD, ADHD, and similar and other conditions.
The story behind why the problem happened after the Concerta, and the nervous habits and tics, is that these medicines are stimulating to the adrenal glands. Some alternative doctors think it is drained adrenal glands behind ADHD, CFS, panic attacks, and other conditions. And people have overcome these conditions with adrenal treatment. So further strain to the adrenals would only further strain the body, stressing it out, which may be the reason for these nervous habits; they are a way to handle the overstressed nervous system.
Magnesium and the B Complex Vitamins are essential to handling stress smoothly, and they support the adrenal and thyroid glands.
I suggest you research magnesium deficiency + twitches, tics.
Here is a post from the internet:
"When I changed his diet to include more magnesium rich foods and less magnesium antagonists, the tics, twitches and blinking totally cleared up in a few days."
