This is one of those questions that appears a million times on bluelight and other boards across the internet, sadly no one can answer, there are so many variables that go into play, its such a case by case kind of question. It not only varies from individual to individual, but for each individual it can switch up too. I've shot dope 12 hours after taking 16mg (which I had been on for months) and nearly overdosed I got so high (now this only happened maybe 3-4 times, mostly I would not feel a thing), I've also had times where I waited three days and I still felt like I didn't get 100% out of the full agonist and then when I took my suboxone again, I got higher from that.
Now in your case, you might be able to get away with 24 hours (I'd try to wait 36) because three days isn't enough for the buprenorphine to completely build up in your system (now granted you were taking quite a bit of subutext, and using a ROA that has a higher absorption rate) but this all has to do with your metabolism. Really the only way to ensure that you're going to get your issue properly is if you keep yourself on a low dose, like 2mg, on 2mg I could always get high whenever I wanted on heroin, even 60mg of oxycodone got me off one time.
