Could it be that meds themselves are actually causing the impulsive behavior? I think a side effect of some meds is "disinhibition," and some of those behaviors you list fall into that category. Maybe it could help to simplify the mix of meds you take or eliminate them one by one to see which is the culprit. your pdoc will have some ideas on how to approach that.

(I started a couple of weeks ago on a new drug and experienced some disinhibition in the first few days, but this went away.)

Good luck.
