It's progressive.
Don't get me wrong, I love a good beer, and I 90% of the time can control myself. It's that 10% of the time that is not worth the risk. My drinking self was becoming more and more reckless. I found myself caring less about my life, because "what was the point anyways, you can't change it", or at least that is what my addict self told me
The percentages you listed there will change, because it starts to completely hijack your life.
