The 'most severe' category for problem drinking is usually ridiculous to me in nearly every study on this subject I've seen, especially in more recent decades.
Lumping together the guy who usually drinks a 6-pack on Fridays with the lady who puts away a fifth of vodka every single day makes no sense to me. There should be much more granularity.
I like it. Reminds me of BMI. It's easy to slip into the warm soothing waters of alcoholism and not even realize it. Knowing that killing a six-pack every three days is on scale with alchoholism can keep you honest with yourself. You can fool yourself into thinking your weight is in check but in reality your two pounds away from being obese (defined by BMI) and developing the associated health risks.
