Forget about the money you actually spent on the booze, although considerable. Imagine how much money you could have made if you had spent all that time and energy on your career or business instead of having idiotic conversations in bars with losers or watching crap sports on TV while drinking. Not to mention how many opportunities were lost due to people losing respect for you because of drinking too much, alcohol-induced anxiety, laziness, loss of self-confidence, etc. Depressing, really.
