I've cut back in recent weeks, to support my wife re: reproductive reasons. I've found that LeCroix sparkling water works for me, as a substitute. I went out with a friend a few days ago, had a shot, and felt really gross - like I had just poured a little glassful of toxins into my body...
Not sure yet how serious I want to get about this, but the benefits of quitting, or at least significantly reducing, alcohol consumption, are pretty clear to me... Sympathy sobriety is definitely a good thing!
