Dopamine, Reboot, Edging, reflections

So a short background.

I did not PMO for 4 weeks because I was very busy with work. In that time I suddendly noticed that I was I general more happy, less depressed, suddenly starting conversation with strangers (not like me usually) joking, sayning my own opinions and what I wanted without filter. Also less general anxiety and less worrying. I also got more enjoy out of watching some humor on TV, that before felt like BLAH. Then I realized that I actually had not pmoed for 4 weeks and maybe that was the reason? So maybe less placebo effect and more real effect of not PMO?

Anyway after that I had a period of free time at home and for some reason I saw and old videofile on my computer that I was not sure what was. I opened it and it was porn. I clicked away quite fast, but then something in my brain said just another look. And after that it escalated very quickly into watching more and more porn for the next 48 hours. I did not cum, but I edged to the porn ( thinking this was better than orgasm)

So I noticed that in the beginning of this porn feast I got turned on just by seeing some girl with sexy clothes in the videos. However after some time I needed more and more stimulus and ended up watching some weird things. I never orgasmed during these 2 days and here is what I experienced.

- Just a small trigger or clue can easily escalate into porn. I did not even indend to watch porn, it was just this videofile with a bit weird name on my computer that I clicked on. If it was porn I was just thinking I could watch a abit and stopping soon. But after I closed that video I JUST HAD to see the other files on the computer also. Damn.

- Dopamine got really high and I was hunting and seeking for more porn and more porn to download. I think this seek, hunt and gather thing is affected by dopamine or opposite.

- Since i didnt orgasm, the dopamine stayed high for a long time and I kept searching for porn for a long time like I could not stop.

- Initially this dopamine rush felt quite good and the feeling of something good was going to happen ( seeing the porn I had downloaded) However I noticed I got immence amount of energy and I had trouble falling asleep and it was diffucult to sleep deep and long. Felt kind of like a mania.

- My mind was filled with sexual images and scenes from the porn I had recently watched.

-The day after I did not watch any porn or masturbated and now I feel kind of drained and depressed. I guess this might be because dopamine got so high frequentlt for these 48 hours without orgasm and now my body has downregulated the dopamine-receptors? Thats why I feel more shitty today?

Questions:

1. Does the artifical high dopamine downregulate the dopamine receptors so that the same amount of dopamine does not feel as pleasurable as before? That means that everyday activies feel less pleasurable and interesting for an addict? (addicts of any kind I would guess?)

2. How much did I hurt my rebooting with this 48 hour of porn focus after my 4 week of abstaining? Did the fact that I edged and kept the dopamine high for a long time actually make it worse?
