For me, sobriety comes first. If I feel like attending an event, I will. I'll also be armed with an action plan in case I have the urge to drink, I will always drive myself and alone or with someone who knows I may leave at any point no questions asked.
I have been in 2 situations so far where alcohol was around.
The first I was 40 something days and the second was a week later.
I have not had any desire to drink, what's so ever. So, that made these situations easy for me to be in. Had I had a craving at any point up to the event, I doubt I would have gone as I could have used my surroundings as an excuse.
I have let go of mostly all my friends that drink, maybe down the road we'll chat again but not now because all they do is drink, maybe not as much as me but I have no desire to be around people drinking.
Many good advice coming your way, I am sure from others
