Nicotine
"I started Habitrol because when I quit drinking alcohol, I started smoking and eating everything in sight.  The Habitrol not only curbed my craving for alcohol, it curbed ALL of my cravings for substances I've struggled with for years.  I stopped using the patch for 2 days, and ate a whole batch of brownies to keep from drinking or smoking.

Don't know how this story will end, but whatever is in this product is a blessing to those of us suffering with addictions."
