Medicinal and social are very different uses.
I advise trying the good stuff, sipping wiskey, Cognac, in small amounts several times a day.
A glass of wine with dinner works. It does curb Social Anxiety, and best when alone at home.
Like sleep, it is a relaxation that gives you the energy to go on. Sometimes I see it as inturnel ear plugs, shutting down the brain echos of the day.
A medicinal use does not show, but it does have an effect. Moderate use is good for you.
"Take a little wine for your stomachs sake."
As for clubs, drink at home, so you start relaxed, then nurse one of their expensive dirnks so you look right. You want to be sobering up when you leave. It gives an advantage, as they spent the night getting drunker.
Us drunk, them sober, seems to work, us sober them drunk seems to work.
Moderation, practice, it can be beneficial.
