Yup, and it can happen the other way too - I get loud, rude and irritable when I'm high, so there's been more than a few group events or training sessions I've realized I'm high in only after I say something mean and have to head off to do some rapid and come back later, but the lows feel even worse because it stops everyone dead (heh) and starts a panic which is more than a little embarrassing when you're already stressed.

For the dance thing though... I don't know how well it would work for you, but what about Just Dance or something like that? It'd be expensive, potentially, and you'd still have to work through finding what works to keep your numbers stable during dance, but it would be a more controlled environment for you where you could have everything right there in the meantime so you can still do something you enjoy in smaller bursts while things get adjusted.
