Not being on psych meds can cause moods to fluctuate. Moods flucuating, it can be harder for you to remember and be as quick mentally. If the bipolar is controlled with the appropriate meds, then this usually decreases. If a psych med makes you loopy or you can't think, you need to tell your pdoc about it so you can look into a different med. Alcohol use is HORRIBLE for bipolar as any other mood altering drug INCLUDING POT. Pot has a similar affect as alcohol and benzos. Mix all three together and you can be looking at an accidental overdose. All in all not good.
