I read that there is a medication in the works to work on the addictive part of the brain. Right now there isn't a cure.  You can stop doing the addictive activity but it's not a cure, just restraint.  Lot's of times it turns into changing the addiction to something else. I quit drinking and now I eat too much candy even though I wasn't much of a candy person before. I also buy more scratch tickets.
how do you cure addiction?
