In doing a table search it appears all the drunk references are still there. The animations may have all been un-preloaded though, so you may need to add them all back to anim_files.xtbl - preload True. You may also have to change the AnimSet reference on the character to Drunk.xtbl and add specific "walk", "run", "stand" tags so that they play properly. By looking it seems there are specific drunk tags that were used and that would mean AI would have to force override the animations from "walk" to "drunk walk". But if you point the characters to specific animSets in the character tables and add the generic tag references they will play as such. You probably won't get the random vomiting though, unless maybe you override the "idle" with "ped_drunk_vmt.animx". There's a couple things to try here.
