I have had problems like bruxism, nail biting and chewing on the inside of my mouth growing up and through adulthood. I still have these periods where I want to chew the inside of my mouth. This is one symptom that has been pretty presistent in hanging around.

This is a nervous habit, which I think is related to my vitamin b6 deficiency. But I actually think my low b6 levels may be doing something to my magnesium levels. Nervous habits seem like they are more about magnesium. But this is one symptom that seems to persist for me.

In the book Enzymes for Autism, the auther calls this the chewies. This is a pretty common problem though.

I will even sometimes consider chewing a piece of gum to deal with that need to chew. But most times I grab a sublingual b6 supplement that seems to work for me.

The bruxism is more damaging to teeth in the long run.
