Okay, so, I thought that I'd make some conclusion here about the journey.
My anxiety is better, my inner child is better, my sleep is better. My cognition and connection to people is better. I don't nod off and I don't need to "act sober". I sometimes get some minor skin discomfort if I have sleep deprivation, but honestly that has sometimes happened since quitting benzos anyway. I consider the withdrawals being completely over.
What is surprising is that even when I was still withdrawing, my bruxism-sort of symptoms were better. They originally started of obsession/compulsion related to hyper consciousness about my breathing and salivation, and so have not completely vanished, but they are much better. Which makes sense because opioids can cause minor jaw lock or sort of. Which is probably mediated by acetylcholinergic function, but I can not claim that for sure. I was really surprised that things I thoght I had been treating, I was actually actively making worse by doing bupre.
Asthma/long covid is worse, or at least the cough symptoms associated to it. I can not exclude possibility new emerging of symptoms is just coincidence, but I don't think so. I am doing inhalators about the cough now. Cortisol and bronchodilator.
Alcoholism is worse. This is such a bummer. But I don't feel same kind of inclination to get stoned every night. Bupre seemed to direct me towards escapism and boring repeated pattern of comfort.
I have done oxycodone 3 times since quitting. It seemed to cause minor setback in withdrawal symptoms, nothing serious. First time, when I had serious set of other drugs too, it was nice, but the 2 times since without all the amphetamine and stuff, I've been slightly discontent with the emotional numbing it caused. I am not exactly looking forward to it, but I guess I am going to do it again. Definitely. Bupre too. But if I do some work about it and I have some luck, I might possibly lead rest of the life without another opioid habit. Statistically not very likely, but I guess I should not think about that.
All in all, I had so many medical reasons to do bupre and still I think I am much better off, I have to agree with people that say commonly opioid habit is not a good thing. I also did very low dose for limited amount of time, and people tell it gets only worse over time. I had noticed pattern that people tell bupre might be effective medication for many things 6-24 months but suddenly it turns against you. This was also one reason I decided to quit. I was confused for a short while and I was inclined to do bupre rest of my life, but I am glad I got out of that delusion and got into this point.
