to be honest with you i sucked my thumb until i was eight years old so i know how hard is to be broke but i broke myself of it. Have you tried getting a prescription for it? the taste alone got me to keep my thumb out of my mouth. but what got me to stop fully was the fact that i had a wart on my thumb and it was wet when i started to pick at the skin. when i removed the top layer i noticed a bunch of spores. i started pulling out the spores that were the same color and got no where but when i pulled out the spore that was directly in the middle of the wart (which was the only one that was a different color)it just went away. and it has never come back. if all else fails try that.
