Some new literature that people may like:

And then a little bit of what I wrote about it elsewhere on the internet:

I'm getting more and more interested in the K+ theory because it appears to be tied to Progesterone. Modulating Progesterone has been a long-term goal of mine becuase I think that it's sufficient to cause the downstream SERT density decreases and 5-HT1A autoreceptor desenitization that I still beleive causes a lot of our PSSD symptoms. Note also that Serotonin can do a lot in and out of the brain, and that this could be doing things too. Once you show that something can increase Prog, I can tie it to each and every PSSD (and basically PFS honestly) symptom.
I searched and searched for something that would control Prog, because I think that might be the next layer of the preverbal "onion" in the PSSD puzzle.
Special note here to the studies below that I highlighted, but I will include a few extra just to back up the claims that it all seems to be part of a bigger cascade, which is outlined at:
https://pssdlab.wordpress.com/neurohormone-theory/
This is why Estrogen and Testosterone can reverse PSSD in rats. When people on the PSSD forum tried Estrogen, some had total symptom reversal. The problem is the cost, the danger, the hassle, and it doesn't seem to last. This means dig a step deeper. If Estrogen is protecting SERT in the POA, then find out what could mess with that. As expected, Prog can. So if we can tie that a step further backwards into K+ levels, then f*** me we're golden.

A question that I do have.
Chicken or the egg? High Prog or Low K+?
Which comes first, and I honestly don't know enough of this literature to say yet... Does K+ decrease Prog receptors? I thought I had read that here? The study above seems to paint a different picture: that lowered K+ increases Prog levels. It doesn't seem to me that decreasing Prog would lower receptor levels, but again maybe I'm missing something and I admittedly have only looked at a handful of papers in this field.
