A guy at worked was scared straight from a Doctor and he used sunflower seeds to keep his mouth busy. Worked for him. Like smoking....anyone I know who has stopped did it because they wanted too. It took some inner strength they didn't know they had but thats what I have been told.

If the test or apointment proves the spots to be nothing more than a warning sign then that should be all the fuel you need to quit!
Good luck!
