This is what I would classify as functional alcoholics. They still "need" the substance to function. If it's only for a block of time, the substance suppresses an emotion, feeling, etc. and helps them to cope. This is also addiction. A person who drinks in moderation will not "need" the substance for anything but just for the pure enjoyment of it. They can go days, weeks or months without having the "need" to drink.
I agree. I think there are different degrees of addiction. It's not just black or white for everyone.
Everything in moderation - but that isn't the American way - let's Supersize it!
