Hmm... highly functioning. Well, my thoughts and experience on being a highly functioning alcoholic having shifted over the years. I thought I was highly functioning in college while drinking - but my gpa could've been higher, I could have won that highly coveted award instead of just being a nominee, I could've had a PhD by now instead of two bachelors degrees, I could be debt free and living in my cabin on my land by now instead of in the middle of paying off the debt and saving for the land. I could've traveled to 20 countries by now instead of 2. I could've published 2 or 3 books by now, instead of being in the middle of the first.
I used to think I was an inspired, creative highly functioning drinker. I could've been much more inspired, more productive, and more accomplished had I NOT been a drinker. I regret not stopping sooner. I wish I'd stopped at age 25 instead of age 36.
Stop now, do yourself the biggest favor ever. It'll be the best thing you can do for yourself.
