For what it's worth I used to almost only experience dysphoric mania so due to PTSD and BPD was not recognised as BP which led to bad treatment options. I am glad you have the right diagnosis and hope the treatment will be more beneficial to you in the future. No euphoria feels like one big rip off to me. Only a couple of times have I had it and it was AMAZING but that was from my perspective, think i was a lot to handle so hospitalised. Looking back I did make a fool of myself so there is that negative. So happy-fluffy-bunnies mania rocks but can be harmful. Still I'd take it over dysphoric mania any day, hands down. 99% of my mixed states/mania's are of the dark variety and it is hell on earth for all involved.

I currently mentally working on a way to switch on harmless euphoria without having any negative effects like following deep depression and embarrassment over what i have done. Think it will take a while to perfect.
