Welcome slc - it's great that you found SR - the place that got me sober and kept me that way after 25+ yrs. of heavy drinking.
I drank at home with my husband too, and we would get into ridiculous arguments that we wouldn't even remember in the morning. Black outs are very serious, and you've apparently reached that point at a young age. Drinking was so much a part of my life that I couldn't imagine giving it up, so I tried to moderate. That failed terribly, but I kept at it for a long time - the result was I drank round the clock in the end. You never have to reach that point - congratulations on your wise decision to turn your life around.
