Not social anxiety in particular but I did get anxiety attacks regularly over lots of stuff including social situations.

Im on 10mg of lexapro (escitalopram) daily now, for the past ~4 months. Its been magical, literally nothing bothers me anymore after being a ball of stress and anxiety for like 20 years.

I also take a 200mg caffeine pill twice a day now, between the two I feel like my brain is on sport mode.
