Good to have you back. There appears to be a lot of people who for some reason fall around 3 months. My previous relapse was also around 3 months, a little more, 105 days. For me it a complacent feeling that I could drink and nobody would ever know, and it would be a reward and how did drinking feel like again.. things like that.
The idea of defending your own sobriety is your responsibility alone. Nobody else can do it for you, I think. This defence means for me avoiding people who are active drinkers, places where alcohol is served, and saying NO when I have to say it.
It is so worth it, sobriety that I wouldn't even matter breaking relationships with people, offending them in a vulgar fashion and doing something that I need to do in order to survive (survival of sobriety). Good luck and congrats on your resolve! The days keep adding up... one day at a time.
