I'm interested in the phenomenon of short term Dysphoria:
Dysphoria is a state of feeling unwell or unhappy; a feeling of emotional and mental discomfort as a symptom of discontentment, restlessness, dissatisfaction, malaise, depression or anxiety.
What interests me is when Dysphoria arises following moments of intense pleasure:
- Post-coital tristesse, a feeling of blues following orgasm
- Postorgasmic illness syndrome
- Dysphoria associated with recreational drug use, where X minutes of euphoria are followed by Y minutes of dysphoria ( I do not know the term for this one).
The phenomenon that I'm describing lasts from 5 minutes to a few hours, then disappears. It is experienced by only a small subset of population.
I tried to look for an explanation, but cannot find the cause - why Dysphoria appears following intense pleasure? Is Dopamine or Dopamine Transporter or D2 receptors involved in some way ? Is this some sort of sensitization/desensitization homeostasis mechanism at play?
Thank you for any search terms or hints that would help me shed light on the subject.
