Jaw pain from prolonged amphetamine use?

[korky8097]

Swim has been perscribed to adderall for 3 or so years now for A.D.D. Until now he has never experienced any clenching jaw or pain, even when he was doing meth and was into getting pretty amped up. Recently it seems that whenever swims normal dose for the day (40mg) wears off, he is left with a clenching jaw that sticks with him the rest of the day and into the next day. The pain is mild, but he wishes to find out what is happening and intends to try to correct it, as he doesnt want problems down the road.

Swim believes it is probably due to lack of nutrition (magnesium perhaps?), as he has been off his huge dose of daily vitamins for a few months now in the form of animal paks. He just never bought more when he ran out for some reason. Has anybody encountered a similar problem, and if so what would be recommended (besides pain killers, swim has thought of that already)?

Thanks
