Cohiba, one thing I've really been struggling with the last two weeks, and struggled with the longer stints of sobriety I've had is the thought of never drinking again forever. I'm 29, so in a similar age range.
I've asked myself the following: When I drink, do I intend to get drunk? Deep down, I know the answer is yes. With that in mind, I don't think I can go back to moderating. Since I'm also not a daily drinker, and probably have the on/off switch somewhere around two or three drinks, I'm not going to beat myself up if I have NyQuil or say a glass of champagne at a wedding or a taste of a local beer while visiting a foreign country, but I know that just recreationally drinking is going to lead to me eventually experiencing more blackouts.
I think 50 days is a great goal. It's achievable and not as scary as "forever." I just wonder if you, like me, let a few beers turn into a blackout night all too often.
