I just know I spent a ton of money on FOOD when I was drunk, and even more when I was high on weed. Throughout college I spent hundreds of dollars on Jimmy John's sandwiches on walks home from the bar. And perhaps most dangerously, I used to go to Wal-Mart after smoking. Naturally EVERYTHING looked appetizing.
Needless to say I am very happy with the surplus of money I now have in my sobriety that went to junk food in the past.
