Suggestion: LSD or LSD analogues in an amount just north of a micro dose. Have had folks report back feeling alert, chatty, and very open to having silly and/or indepth conversations with strangers. That and (compared to a night of drinking) waking up feeling like a million bucks, if a little tired depending on how late they stayed up as a result.

Your mileage may vary (perhaps significantly), but hey, it's an honest suggestion. Comes with its own risks too, but doesn't everything that isn't just clean living and self-improvement? If you end up taking this seriously, I recommend doing a little reading first to make an informed decision (erowid.org has a lot of useful information).
