Your story sounds so familiar. Blackouts, brownouts, I had so many during my twenty-year drinking career I can't even count. My ex-wife even had a name for me on the mornings after: "Mr. Regretful."
I've been sober two-and-a-half years now. On occasion I do still miss drinking, although I know it's nothing I can do again. But I will never, ever, ever miss Mr. Regretful.
Pack it in, son. It gets worse; it doesn't get better.
Good luck on your job interview!
