I blew sobriety twice now, because i put myself in situations where i was "catching up with friends" and they were drinking heavily. I eventually caved because it felt right. Just like old times. Next time I plan to suggest catching up over lunch or coffee, or a shooting range, someplace where no one would even think about drinking. Like the other posters said, might think about changing meeting places.
Good luck, and congrats on all those sober days!
