I managed to see the first episode when it aired, and though I have a hard time staying up late enough to see new episodes I always try (Early work shifts)
One that really struck me was there was a professional driving instructor that was great during the day, then after he got off work all he could think and do was drink jack. kinda struck home to me, and that episode actually got me to calm down a LOT on my drinking. When I watched that I was at almost two fifths per day, now I'm down to maybe two shots a day.
Anyway, yeah, love the show. It's a no BS approach to addiction - I like that approach (unlike news and other shows)
