My first wife was an alcoholic. We didn't know it until after we were married as she was not old enough to drink yet. As a member of the Army, I was sent to Germany and she came along. Once she started drinking, she just never stopped. But the point is, she continued to function normally, or at least what I perceived to be normal. She did everything a young GI could hope his stay at home wife would do as far as housekeeping and such, but she drank constantly. I honestly had no clue how much she did drink until six years later when she had a blackout. It scared the bejeebeers out of me. I took her to the hospital. They did a blood test and told me that at her blood alcohol level she should not even be conscious, much less walking around and having conversations with the medical staff. Alcoholics build a tolerance and are able to function with unusually high levels of alcohol in them. If Bix had reached the same stage as my first wife, I'm not at all surprised he was still able to perform. Aside from that one blackout, you'd have never known my ex was an alcoholic at all.
