Not alone.
I think I launch less often than before I was medicated, but I can really go off. Yeah, there can be some whopping embarrassment when it's over. It's often set off by frustration. Zap! Like a bolt of lightning. Apparently, it can be terrifying to observe. First time BF really saw it, (he told me later), he just got out of the way and thought, "ho.ly.****!!!" Foot through the wall. After throwing myself repeatedly at it. Stormed out and walked about a million miles an hour trying to burn off the excruciating energy level. And still it took everything I had not to run off the balcony when I got back. It wasn't directed at anyone, mind you. I remember so clearly thinking how I wanted to wrestle a tiger. And that I'd win. Totally serious there. Yikes. It'd be hugely embarrassing to admit to the stories I could tell. I'm sure some might imagine some kind of stereotypical raging woman kind of thing -- a lot of screeching at people, big fight kind of stuff. (25 years with ex. Never had that scene.) Which isn't to say I haven't screamed at people. Hell, complete strangers. Mostly though, it's things. Things and myself that really take the brunt of physicality.

In the above story, I remember the excruciating level of energy and how very very badly I wanted out of my own skin, and thinking there was no way a state like that could be withstood (physically/mentally) for any sustained amount of time. Then I had a really bad mixed episode. And felt that way way too often. It was horrid beyond words.
