People don't understand its not the amount you drink that makes you an alcoholic, you don't have to be jobless and completely wrecked down the park on 2 bottles of vody everyday, its if you can't go a day without consuming alcohol, your alcohol dependant.
Then a lot of people 'wind down' with a glass of wine or pint of beer as matter of course everyday after work, I think moderation is key as with everything.
Four can is too much according to recommend 'safe' amount of units
