My main drug of choice is alcohol. I didn't get into other drugs so much, but I do struggle with food addiction--ANd other things, like compulsive spending, etc., and I used to smoke alot, too; I used to smoke 5 packs a day before I quit. It was my mental illness that opened the door for those addictive behaviors. I heard that those of us with MI have a higher rate of alcoholism and/or addiction. It does suck.
