Did everyone have a bite block? Kevin didn't.
I know when I worked in the dental profession bite blocks were tough. They are way back between your molars to keep your tongue back. You would produce more saliva having it in there because your body is trying to get it out. They may be able to use a pediatric one that wouldn't gag him as much. Just a thought.
I'm just curious to know if everyone had one.
I know Xanax worked for Kevin on a couple of other things. He said it has a pretty immediate effect. Hope you find something that works.
