Yes, it does. The extent to which it does so depends on how drunk you are. It will also eventually decrease some of your stats based on intoxication level, and if you're really drunk you will sometimes stumble/trip and fall when trying to walk around.
Thanks for the feedback and support! Weaponry and other frightening/intimidating things tend to raise your speaking ability, and may also raise/lower other stats.
Sure. It might take me a bit though. Out of town presently.
