No, I never noticed a mood episode change. Sure, I may notice that I might feel a bit more talkative or giddy when drunk or even a little more down the next day, but it is a short lasting thing, so I couldn't call that an "episode". I think it's a good idea to remember that yea, we may have depressions or manias that last for a long time, but every emotion or reaction to drugs (or whatever) that we have is not necessarily a bipolar thing. If everything that excites us becomes "mania" and everything that brings us down becomes "depression", than what is left?
