Aside from various psychological therapies, or maybe even simple practice (e.g. Taostasters), there are different drugs other than alcohol that help people with social inhibition. Some legal, some not. Ecstacy in moderation would work quite well for what you are talking about, but it is obviously illegal, and if you have an "addictive personality" may be a problem. There was another thread about a legal supplement that the OP mentioned worked very well for social inhibition problems. Sorry, cant remember what it was, but I'm sure other members will chime in.
