Alcoholic behavior at a bar without having any alcohol? I am a recovering alcoholic sober 11 month.  I do not crave alcohol, or need it anymore. I have adapted skills that I am no longer depressed. but enjoying life again.fun, happy, with good social skills.  I have treated myself to a month in Mexico were I have vacationed over 20 years drunk at beachside bars.  This first week, I headed to the first bar with a big party crowd.  I have met 15+ people of what I used to be like.  After 3 day same time they are all drunk and acting crazy.  By the time I left all 3 days I could swear I was drunk, lost all inhabitions, over talkative Without any alcohol. Any still no craving.???
See the placebo effect, it's been known to work in situations right up to double blind studies on dogs. Very weird. 

Also, I would guess you would consider yourself a people pleaser? I forget the name of it but there's a phenomenon whereby individuals begin to imitate their cohort (mirroring?, Stockholm effect?)
