Hiya Auchieshuggle,
I'm almost 39 years old and on day six after frequent binging for the last two years. My binging was usually three times a week with a "never again" after each binge. I made it two, three weeks a few times within that period. Prior to the binging pattern I had been a pretty much daily drinker for a long time (~8 years of increasing amounts).
My recent blood work was okay with liver function in the normal range for all values ... I know that is not conclusive by itself but Doctor didn't think further investigation was warranted based on my interview with her so I am happy to stop worrying for now and just focus on building new sober habits. I don't expect I will be able to dodge too many more bullets!
