Hi Polekat, welcome to PC.
I actually don't have euphoric mania. I have dysphoric mania and mixed states. I don't know if it's because I also have "dysthymia" which I guess is like a constant low-laying depressive state. So, with my dysphoria I am super irritables. I have racing thoughts, pressured speach, obsessive thinking, grandios thinking, insomnia (or sleep without rest,) and I pace and rock and although I have energy I can't seem to focus it anywhere. My attention span drops and I have to do 10 things and once (and nothing gets done.)
If I did have euphoric mania it was before diagnosis when I was a teenager/young adult, and I can think of some times when that might have been the case.
I also have episodes (or melt downs) and I have issues with SI when I'm dysphoric. My mood chart looks more bipolar than me.

I'm depressed today. But I'm bursting with engery! Mwahaha....
