I can definitely sympathize with alcohol improving me in some situations. When I'm at social gatherings sober I'm in my head a lot, overthinking. A couple of drinks in though and I'm not using my analytical brain, I'm using the part that is good at improv, and I have much better conversations because of it, and usually comes away from those events more positive than sober.
Everything good that ever happened in my life was achieved by being analytical. Including eventually getting married.
