Ironically, this is one of those areas where one hang-up can impact another. This is one of the reasons people drink socially, although if that's not an option simply adopting the mindset of 'whatever, they've dropped inhibitions, I can too, even without drinking because that's what everyone will chalk it up to' might be handy.
At least in situations where that's appropriate.
One other thing to remember is that more social people get rejected more than people who are afraid of rejection, they just keep the overall rate of interactions so high they don't have time to focus on rejections.
Of course, that's not always an option for people because we don't all have the social energy to maintain a high rate of interactions.
