The TCA side effect list reads it can cause extrapyrimidal symptoms. Within 12 months I developed the bruxism,but I also had this other issue where my top teeth and bottom teeth would collide shut right on top of each other when I was speaking to someone.

It was as if I was taking a bite of air,and then I would grind my teeth around like I was rabbid or something like.

I then read up on the sideffects and my neuro now,advised that I have developed extrapyrimidal symptoms of which tongue/mouth/jaw are the most common. I then read on about other worse symtoms such as lick smacking,thrusting hips and the like.

Holy Cow... Holy Sheep is right!

That's when I decided TCA's are not a good thing for me. By that stage I was on 300mg divided dose. That could have sedated a horse. I'm lucky all I have is the bruxism and teeth slamming. It could have been worse.
