once you get intoxicated, the bartender cuts you off, so you cant spend 1000gp on drinks (it only takes about 4-5 to get drunk)

i also dont spend any money on drink because it doesnt teach you anything. its like talking to generic civilians (ie peasent, nobleman etc). if they dont have a name, its not worth talking. unless its the first time you've played the game, because you CAN pick up a few hints on what quests are there to be done

as far as what room i rent, doesnt make much difference in BG2 for 2 reasons.

1. you have so many hit points, the 2 extra HP healed by sleeping in more expensive room is not worth the mouse click to change your selection from default
2. all remaining healing spells will be automatically be cast when you rest, which will usually have you fully healed before you even start sleeping. If it doesn't, the +2 HP healed wont matter either
