Can you go 7 days without drinking? If you can't and you relapse you might definitely be an alcoholic
Yes, but I've also been blackout drunk, more than once. I can't really keep beer in the house, because much like a binge eater with sweets, I have surprisingly little self-control and will consume it all in little time.
I recognize I have a family history of addiction. I also recognize I can slow down and moderate, but honestly with no level of alcohol consumption being safe for our health, why shouldn't I just quit altogether?
I find hard rules easier than moderation. Eg currently eating Paleo, which is much easier for me to do than "trying to be moderate with breads, dairy etc."
If you know what works best for you - absolutely do that!
