I fell into the bottle myself, was lucky to get out of it 7/12/96.
Most of my friends then were the fellas who hung out in the alchie and druggie corner in the park. Quite a few of them are dead now, at least three AFTER they quit and got their lives back. Others, I lost track of them.
It gets to where you ain't doing it to feel better, but to wallow in it, punishing yourself for living but pretending this shit is gonna make it endurable somehow when it ain't.
Granted, this is the extreme end of addiction and cigarettes ain't hardcore drugs, but for some - too many - one leads to another, then another, and another,,,
Better to face into the wind then to try to hide from it, because there ain't any hiding from it, and life is too precious to throw away,,,
