If you're more than a moderate drinker, you're an alcoholic. I don't care whether the person is actually physically addicted to alcohol or not, it's damaging their health and they're using it for more than it should be used for.
Moderate drinking is good for you. Heavy drinking is not.
The definition of moderate drinking is between 2 and 4 drinks a day for a man and 1 to 2 drinks a day for a woman.
