The reason Bruce doesn’t drink isn’t because he is afraid of the big guy getting out, or that it doesn’t affect him some how. He is afraid of how bad it will affect him. He’s studied genetics, he knows he could easily have inherited his Father’s alcoholism. And if there is one thing he is more afraid of turning into more then the Hulk, it is turning into something even remotely close to his Father.
I agree, though, by the way, did you now there was an issue where the Hulk literally got himself drunk before he changed back just so Banner couldn’t get far?
Anybody wouldn’t happen to know this comic where Bruce is really old (only because the Hulk’s kept him alive) and they’re like the only inhabitant of Earth (because it’s been nuked or some shit)? The name escapes me but I know I’ve read it.
