This sounds like acute mania to me. I've been there many times. I would become premiscuous. I would spend money I didn't have on major shopping sprees. Things would come out of my mouth I normally would've kept to myself. I talk to anyone and everyone and expose things about myself I normally wouldn't. Acute mania can be quite self-destructive if not kept in check. My last acute manic episode I gave myself a drastic hair cut. Fortunately it came out good. But that could've been potentially disastrous.

So no, I don't believe this to be "normal" behavior, but normal for acute manic episodes. TgrsPurr, xo.
