Emotionally volatile, physically tired, yep. I’m definitely experiencing sub-drop.
What is sub-drop? It’s an emotional and physical low, that begins anywhere from a few hours to a few days after an emotional/endorphin high and can last hours to weeks.
The specific term sub-drop comes from the kink community, because it’s typically experienced by submissive individuals after an intense scene. However, top-drop is, from a biochemical perspective, the same thing only experienced by the person taking a dominant role in the scene.
