Just thought you should realize this is anecdotal. I'm diagnosed with MTHFR and my B12 and floated are coincidentally very low (measured within 1 week of NO). My anecdotal experience is NO calmed my tics, despite being stressed, hungry, and uncomfortable for hours. The dental assistant even noticed it improved and the tics I was concerned about didn't occur.
Going to the dentist is stressful and that alone can increase tics. I'm over here looking for a range of experiences and you are quoting an anecdotal experience unrelated to the question as a scare tactic.
