SSRIs are well known to cause temporary and often even permanent sexual dysfunction. The mechanism is not known for sure but some believe it has to do with downregulating norepinephrine and dopamine receptors. Too much serotonin supposedly does that.
Is there a substance, that would do to norepinephrine or dopamine the exact same thing an SSRI does to serotonin (and subsequently the other neurotransmitters)? Like, if an SSRI makes you permanently blunted and way too relaxed because now you have more serotonin or more serotonin receptors, and less dopamine and norepinephrine, is there a substance that would make you more excitable, make your fight or flight system more ready, make you produce less serotonin or downregulate your serotonin receptors and increase permanently norepinephrine and dopamine?
