I used this a few years ago after biting my nails for over 40 years. This stuff seriously works. It doesn't wash off so it persists for days and days. If you put your fingers in your mouth the taste of the formula is so foul it actually taints your ability to taste your food. Highly, highly recommend because I still don't bite my nails.
