Withania Somnifera, more commonly known as Ashwagandha, appears to be able to be more effective at decreasing social anxiety when paired with alcohol; doses too low of either to be seen as effective appear to be highly effective when combined.
The anxiolytic (anxiety reducing) effects of Ashwagandha have also been shown to, in rats, reduce spikes in anxiety that are a result of cessation of chronic alcohol consumption; basically, possibly able to prevent anxiety from increasing as a result of quitting alcohol.

If you need a big bag of the powder, let me know! I have good sources.
You can take one teaspoon before bed in a glass of warm milk and it’s even more effective if you add a little bit of tumeric to it. ( it’s commonly found in recipes called Golden Milk.) I’ve been using it in my adrenal Stress Relief Tea for about a year. Unfortunately I backed off over the summer and only recently started back on it.
