It isn't a matter of how much or how often you drink. It matters how alcohol affects you. If it has caused problems in your life, then that's something you should look at. A person doesn't have to drink every day or even once a week to be alcoholic. Binge drinkers can go days, weeks, sometimes even months without drinking, but when they do drink, they almost always drink more than they intend to. They can't just have one or two drinks and then walk away not wanting more.
