Minnesota based Co May Have Answer to Stop Compulsive Behavior
If you have a compulsive behavior, this may be the answer to stop, or at least bring some awareness to it.
I have had the nail biting issue since I was a kid. Sometimes it's worse than other times, and it does seem to depend on the level of stress. Just picking or biting or whatever. Some people have a hair pulling issue, or any number of other things.
There is now a bracelet that reacts when the behavior happens. It vibrates just in order to bring the subconscious behavior into the conscious.
HabitAware is a company based in Minneapolis, and has the bracelet available for purchase. It works with an app on your smartphone.... kind of like a Fitbit fitness tracker.
