Not necessarily. It's not gambling, video-games, or pot, alcohol is physically addictive and restructures the brain of an addict, making it (alcohol) a vital substance. Hence cold turkey quitting of alcohol can kill a person. Probably not in OP's case, I'm just saying that it's not as easy.

Yes you're right but the OP stated he's already stopped (a few times) with no physical withdrawal symptoms which leads me to conclude (and I think the OP already feels this) that they are not physically addicted.

Of course we'd all agree that the OP should probably seek medical support regardless of the rambling of a few people on the internet :)
