Stuffing

Whole 12 pack of Mountain Dew

Just a two liter 😅 But I really want to build up to drinking more in the near future!

Best I did was 5.25 litres in one sitting back in the summer. Had some online encouraging and this really helped.

i cant drink much soft drink, but put alcohol in it and that changes everything!

6 liters of milk and coke over about a hour. Super bloated afterwards

How others said, it depends on what you call one sitting.
Quickly just with burps and breathe i can do something between 1,5 and 2 liters, but i am not highly into fast chugging (somewhere in my beginning i did it too fast and puke )
Slowly (i mean 1-2hours) i can do more than 3 liters, once time i chug 4 liters what is my record.

Honestly not much. I drank maybe half a bottle before giving up. Cheers to everyone here who could drink more. It has something to do with a belly capacity or something, I don’t know.
