mint is not good for some stomach things like hiatus hernia, acid reflux...

one of my tricks is to let my tongue be nervous. I let it run back and forth along the backs of my upper teeth and up behind them along the roof of my mouth. no one can tell i'm doing it and it soothes me and keeps me 'busy'.

I discovered this when looking for a way to keep my composure when attending visiting hours at funeral homes because I would be so emotional and when I got choked up I couldn't speak my condolences; keeping my composure meant keeping my jaws clenched. I wanted to be able to give my sympathy with a reasonable level of heartfelt emotion.

It's soothing, invisible, and does encourage saliva production.
