cine, those are good signs that your nervous system is recovering.
I would take that information about inositol reversing serotonergic downregulation with a grain of salt. Here's a 1997 study Controlled trials of inositol in psychiatry
that may be the source of the information. Note that it was done during at the dawn of the SSRI era, when everything was attributed to serotonin and serotonin receptors.
As near as I can tell, inositol contributes to the maintenance of cell membranes. It has the reputation to be calming. I took it for a while. I also took lecithin, phosphatidylserine (Seriphos), and niacinamide. I made a note that lecithin was calming. (Maybe I'll try it again.)
Razzle -- if you cannot give traceable citations, please do not post vague information about how some authority thinks something, especially alarming or misleading information.
As for the relationship between serotonin, dopamine, and sexual response -- SSRIs affect dozens and probably hundreds of neurotransmitters, neurohormones, hormones, etc., not just the Big Three serotonin, dopamine, and norepinephrine. Many important neurotransmitters and feedback loops haven't even been identified.
SSRIs affect dopamine, true, but that doesn't mean their effect on dopamine has anything whatsoever to do with PSSD. It is more likely some other hormone or group of hormones or feedback loop or timing of hormone release is implicated in PSSD.
The folk wisdom about dopamine is that it is the feel-good hormone, therefore associated with sexual pleasure. This is as true as serotonin being the cheerful hormone.
I would hate that anyone try a dopaminergic, which can cause serious movement disorders, in a misinformed attempt to treat PSSD.
