I've been in your position 3 times. Each time at about 140-200 mg/day for about a month with real oxy, only the last time I also mixed in some heroin as well. You are at a somewhat lower dose, but for a much longer consecutive period, and if it is indeed a fentanyl analogue it might be a completely different story.
The first time I went "cold turkey" with only 1 low dose suboxone the first day. At the end of the second day I felt quite tired, but didn't know or expect anything super heavy. I drank some alcohol (1 or 2 glasses, not that much, with no opiates) and completelly crashed. I suddenly got so tired and felt so bad that I had to stop walking my dog and struggled to get home. The next 4 days I could hardly walk and reach the toilet. I also never experienced any pain in my hip, but I felt some weird things during running the days prior, but I was on oxy then. Apparantly got some nerve pain due to running which was blocked. For 5/6 days I could not sleep longer than 1.5 hours, which really messed me up. Even any benzos like midazolam could not cut through that withdrawal. Obviously I called in sick for and could not function. After 4/5 days it was getting better, sleep slightly improved but it took 2 weeks to regain some natural energy.
Next time I was on a lower dose for 2/3 weeks (about 60 to a 100mg/day). I fast-tapered using methadone using some advice on this forum dosages were (18mg, 15mg, 12.5, 10, 7, 5, 2, stop). This was way more comfortable, I felt OK all day, could even work out during the taper, and after it was done my energy was low for 3 to 4 days but I could still function. I just felt lethargic, and I slowly felt better and better.
Next time I was on multiple weeks of oxy and heroin (200mg/day for 3 weeks). This time I tapered using suboxone for 3 weeks, starting at 5mg, 4mg, up to a couple of days 0.2mg, and then quit. Those first 3 weeks I felt ok, could work out, felt a little tired, expecially when dropping the dose below a certain point, but you gotta get through that. The hardest thing was the first day not taking that 0.2. Which was the difference of a normal day to a day feeling your soul was sucked out. After 2 days I decided to give Kratom a try (never took that before) And the moment I took Kratom I felt an Immediate uplift, I could work, had motivation and felt happy. I realized this was probably prolonging my withdrawal, but I used kratom at 10g per day for 5 days anyway to catch a break. Right now I am on the second day without kratom and I feel ok, music gives me happiness, but after half a day of work I am super tired and lethargic. I sometimes have to sleep 1 hr mid-day. Any upper doesn't do you any good, redbull even made me feel worse. I can sleep for about 6 hours, but the nights are not the best. Benzo's aren't really helping, I tried. What really helps is Clonidine for the night (and day as well).
For me cold-turkey is definitely the fastest and quickest recovery, but it's quite rough and horrible those first 5 days. everybody claims it's so hard psychological, but I find the physical part way worse. I can easily set my mind to not taking something, but especially no sleep and no natural energy are the hardest thing to deal with.
I tried tapering using oxycodone once too for a few days, but since the half-life is about 3.5-4hrs compared to 24/36 for methadone/suboxone, it is much harder to taper. You need to plan your doses carefully, and you will notice that you don't get high at first, and then a week in, you will feel slightly worse, tired, etc. At that moment you must stay strong and not up your dose again, but try to remain stable so that your body/brain adapts to that dose, and then continue to taper down. I found that much harder than methadone/suboxone. I even split my suboxone dose at morning and before bed to not wake up with withdrawal in this last time. With oxy, I would always wake up with stiffness and pain.
If you have any responsibilities, tapering is the only viable option, and you will spread it out over a longer period, but you can function and will feel OK. Having some kratom for emergencies is really nice. Clonidine will help you as well if you can find it (basically opiates upregulates your nervous system activity, to stay awake while taking depressant medications, once you quit, your nervous system will be firing constantly, and clonidine reduces that)
Sorry for the long reply, good luck!
