Welcome to KTC dude.
First things first... Stop playing with fire and flush that evil crap. What's the point of keeping it around? That half tin is no motivator to quit... It's an invitation to exercise, and give in to, your addiction one more time. And, yes, you heard me right... Addiction. It's not a habit. It actually takes more guts to annihilate your stash and REALLY jump on the cold turkey bandwagon. You've proven that in the past the temptation was too great for you by stopping over and over... Get rid of the temptation. Right now you're leaving an open door to fail... Get rid of the option and join me in some REAL quitting! You've come to the right place, now... Are you willing to do it the right way? Lets do this man...
