I get it, lots of subs get it. I think Doms get Dom drop and maybe that's different but probably similar, a reaction after the intensity and the connection and the adrenaline?
As Bleue D'âme from L'heure Bleue says, "that drop, it's an actual thing. It's kinda doing my head in a bit."

Someone else mentioned it yesterday. They didn't call it by name, but clearly they knew it could happen and because of that decided not to have a session. They were avoiding the possibility of sub drop.
I've never avoided play because of possible sub drop, though maybe I should have sometimes. I never really expect that it will happen to me. I'm normally a fairly level person. Oh stop, I see you snorting and rolling your eyes. Yes you.
I think with sub drop, because it doesn't happen right away, like the second I'm finished the session, I don't always connect the dots and realize what it is and what caused it. So... sometimes I recognize it and sometimes I don't.
What I know about sub drop for me is that I get emotional, clingy, dramatice. I'm cold. I'm a bit self destructive. I medicate with food.
I just googled it and there are tons of articles... I'm going to research. I will be back.
But in the meantime if you have stories or good suggestions or bad suggestions or, please comment. You guys are the experts, I think we are all the experts, right?
