I was one of those who started very young and lasted a long time. How? Rigid, obsessive control. For years before I lost control (because every alcoholic does in the end), I didn't enjoy drinking -- I just managed my addiction. Some people might say I had a good run, but it wasn't very good.
Sometimes, those who get sober young envy the ones who had the long run. Believe me, we envy you more, because you'll have a long run of sobriety, which is so much better!
