Oh I grind my teeth too! In fact I grinded so badly that I had to do a root canal =p so by right before I sleep I have to wear this rubber like thingy to prevent grinding. Most unglam. My old man kept laughing at me cuz I looked like eeyore (Dragontail - now you know where I got the donkey from right?) I stopped wearing liaoz... Hahaha!
