I think that you show little understanding of addiction. I don't drink, not because I have a problem, but because I don't like it and I'm shit at it. I found that I turned into a bigger dick than normal after a few pints, so I thought, what's the point.
Some people get addicted and apparently, it's one of the hardest things to come off, not to mention the problems it can cause in relationships and with work, kids, basically every aspect of life.
If anyone is beating the shit out of their addiction, then they have every right to shout if from the rooftops in my opinion. Good on them and even better for those who love them.
