Same here.
Oxycodone replaced amphetamines, with a lot of benefits (addiction aside).
I'm since more than a year on 20-30mg/day, golden rules. I don't want to take more and increase my tolerance. I use oxy to keep my health stable, i'm happy enough to feel well.
But I feel you on this. I strongly advice you either use a potentiator (Proglumide works greatly) or make some breaks, or try something different. If from opioids you are seeking the euphoric / energetic / stimulating effect, then give a try to:
- Tapentadol (cheap, OK kick, but least less and it's weaker)
- Tilidine, even if oxy tolerance is high, on me it still works GREATLY, even with 100 mg orally taken. It least 3-5 hours, it's a very stable and energetic high, and costs 10x less than oxy. One of the most underrated opiates IMO.
- Hydrocodone (pure or CWE, not this crap with ibuprofen inside), sadly if you have high oxy tolerance won't work
- Oxymorphone (opana), no needs to add anything else. It's simply the best for this.
- O-DSMT. Like tramadol, acting on Dopamine receptors, and not being so risky (still you need to pay attention) like tramadol, PLUS it's legal on most country and least long - could be your perfect match.
If you live in EU or Sud Africa, you may try to find the holy grail of opiates: Ketobemidone, Piritramide or Dipipanone. I'd give a kidney for those ones :D
Hope my advices will be helpful.
Best regards
