I demolished a mixture of maybe a dozen tall boy bud's, 6 pints of guiness, 4 gin and tonics, 3 white russians, a sea breeze and 4 lychee and amaretto drinks I mixed up, though I dont remember what I callled em. So thats I dont know 30, but it was over a 14 hour period, so it may not be the same, wasnt all in a "night"
The amaretto lyche shocktails I made were made by me, so they were kinda big and sloppy.
