Chekushka

Right-clicking the bottle drinks it in about two seconds and leaves an empty glass bottle behind. Each drink raises the Drunkenness effect by one level, up to level IV, and extends its duration by 90 seconds per drink. The effect is shown as a drunk-style camera sway and aim drift rather than a tinted screen, and sobering up starts the count over. Each level slows movement by 6%. A drink also clears Weakness and grants Strength for 30 seconds.

After the fifth bottle the character starts vomiting, losing two hunger points and leaving a puddle where the vomit lands; a walker moving through that puddle is slowed as if wading through honey, and the puddle evaporates within a few minutes. At the tenth bottle the player is poisoned for 15 seconds with nausea and a message about alcohol poisoning, and at the fifteenth the poison rises to Poison II. Sneaking and right-clicking a block sets a bottle on the floor facing outward, and right-clicking it picks it back up. Breaking a placed bottle drops the item.

A server running it needs every connecting player to have it too. Files are published for Fabric, Forge and NeoForge for 1.21.1 and for 1.16.5 – 1.21.1 across five game versions, and Forge also has a 1.20.1 build.
