That is an excellent Idea~! One thing I do is take music with me like a walkman . I sometimes have a hard time if I have to drive to places I am not familiar with so the radio really helps in the vehicle too. I also like Kimmy's idea . I do that too. Or chewing gum. That seems to help with tension sometimes too with me.Hope these ideas help you out.Take care and Good luck!
