If we are talking shots (and I am), then that's 45*11 about 500ml of vodka. Back in my drinking days (I've been sober for almost 2 years) that was "A solid start." And if I got that deep, I was sure to finish the rest of the 750 ml bottle just for the fuck of it, and probably have some sambuca or jungle juice, to finish up, and I probably would have started with at least two pints of beer. By then it would be kebab-o'clock.

Like "almost a whole fifth" lot of vodka.

It’s fine, it’s less in metric
