Night of my Lechaim after I walked my (at the time, future) wife home, I circled back to a group of friends to have a farbrengen. At this farbrengen we had a bottle of Spirytus Vodka (96% alcohol). At the beginning of the farbrengen I poured about 4 oz. into a separate cup (see here:

After drinking the first Lechaim from a shot glass, I drank the entire cup of seltzer, for some reason my mouth was getting drier, when I finished I realized that I just drank the entire cup of neintziker.
