Hello Grace,
Welcome to the NeuroTalk Support Groups.
I hope you're able to get some answers when he sees the Neurologist this week.
He's not grinding his teeth in his sleep is he?
In the meantime you could ask over on the
Medications & Treatments Forum
"For discussion about medications and treatments for any
disease or health condition, including issues of medication toxicity."
You could also try a
Forum Search
take care there.
