There are hundreds of threads detailing various methods of the 'best' way to get thru opiate withdrawal. We even have a mega thread dedicated to it, which you can find via the search engine.
But lemme just say something. While comfort meds are nice, in my experience they just prolong sobriety and 9/10 times when I try to detox using benzos and whatnot I just end up eating them like candy, doing stupid shit, and relapsing.
I have gone thru withdrawals numerous times, and honestly, the only few times where I got thru them the easiest and was able to stay clean for a bit was when I had to kick in jail. I'm dead serious. Opiate withdrawals are VERY seriously effected by your mental state going into it, and during the detox. Everytime I have kicked in jail, it hasn't been pleasant, don't get me wrong. But your mind KNOWS you can't get any dope, pills, comfort meds, or anything. It just accepts it and that is the key to gettign thru it with ease.
In jail, my mind knows the game is over, and after 3 or so days I'll start feeling better and by day 4 or 5 i'll be eating normal and probably 90 percent back to normal.
It sounds fucked up I am sure, but I am totally serious with what I say. Now I DON'T recommend getting yourself into trouble/going to jail so you can detox, lol, but I was just trying to illustrate the point that many symptoms of opiate withdrawal are psychosomatic.
I gotta run but I can type more later if you have any specific questions about withdrawals; I also have vast experience with all of the 'comfort meds' you listed. Feel free to ][D r I v A t E message me as well if you need anything or just wanna chat about withrawing. Just stay stroing man, you'll be fine. Luckily you aren't on a very high dose of oxycodone so it shouldn't even be quite as bad as you may think.
Good luck brother!
