Congrats on 8 days!
Envision how you're going to stay sober through your work function. Practicing it in your mind before hand makes it easier to execute at game time.
Then, beware the 'day after voice'. The one that comes around the next day to say "well done on getting through that drinking function without drinking. You deserve a nice reward!"
Embarrassed to say I fell for that more than once.
Way to get it done!
