I also chew the inside of my mouth, which as a result of the grinding of the teeth, has caused receeding gumlines. So, I wear a night guard
as much as possible to try and stop the chewing. I do notice that when my pimples on my arm and face clear up in the summer from sun, I stop picking so much. But when I am tired or stressed, I will sit under a light and pick my arms forever!!!
I've tried Lexapro and it doesn't really help. The only thing I can do is try and make myself stop.
