The true answer at the moment is just full abstinence, and taking one day at a time.
The reaction I have is so severe that its debilitating, no matter whether it's from sex or masturbation.
I think it's in part due to how addicted I was to pornography, and I may be dealing with some glial-priming effects as well in the brain, and / or dopamine & opioid receptors that are kindled / over-excited.
For me, the POIS symptoms feel like extreme Alcohol / Benzo withdrawal, which is a nightmare on earth. Tremors, insomnia, hyper-vigilance, bi-polar reactions, depersonalization, burning blood vessels, pain in every part of my body, you name it.
Another element that could be at play is psychosomatic, because now I am correlating sexual activity / gratification with an immense amount of guilt / shame due to my focus on overcoming this addiction. I cut porn cold-turkey back in September of last year.
For me, I think it's a lot of comorbid issues:
* Gut Health / IBS (hence part of the supplement stack + probiotics + new supplements on the way)
* Immune Health (hence the other part of the supplement stack + diet changes)
* Viral Load / Contracting HSV1 within the past 5 years (re: detox foods)
* Radical change in my diet mid-last year (went very clean, very abruptly)
* Abruptly stopping omeprazole (used daily for over a decade)
* Abruptly stopping pornography
* Experiencing intense food poisoning middle of last year / ER Doctor put me on Bactrim which I had an extremely adverse reaction to (and may have wiped out my microflora)
* Prostate Damage, which is inflamed and may be infected (occurred middle of last year, thought nothing of it, visiting a urologist next week)
* Dealing with cognitive swings (anxiety / depression / anhedonia) due to dependence-like withdrawal of my pornography addiction (balancing dopamine / opioid receptors)
* Anxiety-induced Hypochondriasis (hence all of the above)
I developed POIS in the middle of last year, after all of the above happened.
Other stressors can also now trigger POIS-like symptoms for me including sodas (excessive sugar / caffeine) and alcohol (half a beer will do it).
