I (30M), have been invited out to drinks tomorrow after work. The last time I've went out for drinks was nearly two months ago and I was taken advantage of by a taxi driver (money extortion) because I had drank way too much. I've really enjoyed being sober for two months and I just know that tomorrow night will be another night of drinking. I'm anxious of what may happen tomorrow night and I'm also considering bailing altogether. 

What would you do if you were in a similar situation? Any advice or tips?
