Lara,

Thanks for the great information on Tourette's syndrome. From now on, I will have to say, make sure you don't have chronic Lyme disease rather than Tourette's syndrome. Here is something else then that might be helpful for PearlDoves - "The central role of magnesium deficiency in Tourette's syndrome: causal relationships between magnesium deficiency, altered biochemical pathways and symptoms relating to Tourette's syndrome and several reported comorbid conditions":

I am trying a new (for me) magnesium supplement. It is called Ionic-Fizz Magnesium Plus by Pure Essence Labs. I've only had two doses so far, but I seem to be getting positive effects from it - more so than other magnesium supplements I have tried in the past.
