In this case I feel like a hopeless addict trying to rationalize his addiction in any way possible, but people who want to drink REALLY want to drink, and they will find any rationalization available. There needs to be unassailable reasons telling them that they shouldn't, in order for them to be effective.
There's also something called kindling that makes each withdrawal episode worse than the last, and is believed to make frequent binge drinking especially dangerous. Besides making withdrawal worse, it's associated with cognitive deficits and mental health problems.
Then, there's the increased risk of traumatic brain injury that comes from being drunk, especially if you're crazy enough to drive drunk; or the increased risk of deciding to play with a flamethrower after a few shots of Everclear.
Definitely get your vitamins if you're feeding an alcohol addiction, but know it's harm reduction, not harm elimination. As far as I can tell, there is no known way to make heavy drinking safe.
The real danger with alcohol is that unlike hard drugs (heroin, cocaine) the destruction takes years and it's very possible to trick yourself into thinking your consumption is fine by leading a normal life alongside the alcoholism... until it's too late, and then there's no turning back.
