I stopped attending functions like that unless it’s full of like minded individuals; obviously, your associations that promote drinking are not.
Remember that People, Places & Things (you do) have to change for Change.
I totally agree with @Dazercat.
Godspeed
How did it go?
I don’t think it could have gone much better. I prepared myself for drinks being handed to me. Brought my supportive best friend, and guarded myself with the truth I have found in sobriety. I cautiously observed as people threw back more and more drinks… it was not appealing. I was trying not to judge but I did. I left early 
Snuggled with my puppies and got up early to go to the gym. Thank you for checking in 
You are awesome. Well done!
