Your story sounds like mine in a lot of ways: I also don't fit the stereotypical demographic for someone with a life-altering alcohol problem.
I drank on Sunday, was out of commission all day yesterday, and here I am again starting a new day with a new resolution.
I just joined today and I'm looking to take an active role in getting a grip on this, so if you ever want someone to set recovery goals with, I'd be up for it.
