I don't get it how people differentiate between Subutex and Suboxone, and Zubsolv is still the same medication only better absorbed, supposedly. It's the same active compound - buprenorphine with or without naloxone which is harmless. Buprenorphine's affinity to MOP receptors is ~3x higher than that of naloxone (source), the dose ratio in Suboxone is 4:1 with a much lower s.l. BA for naloxone vs. buprenorphine (source). Also, naloxone's half-life is only up to 1h, so the minuscule quantity that gets into the circulation is mostly gone by the time buprenorphine really kicks in. Under no circumstances naloxone antagonistic properties should have an effect on buprenorphine effects, so saying that Subutex is a little stronger than Suboxone or that you'll get a stronger buzz off Subutex is untrue. There are many stories of people switching from Suboxone to Subutex and still feeling withdrawal despite being on the same dose, it's all due to autosuggestion.
The reason why opioid effects from buprenorphine diminish over time as you take more doses is because it builds up in your blood and occupies more and more receptors. That's what happens initially. The so-called "honey moon" phase has probably more to do with long-term tolerance (the change in effects may relate both to MOP and KOP receptors). That's why unless your tolerance is incredibly high, you never really need doses as high as 24-32mg. It's best to stabilize on the lowest dose possible, I guess you'll have a bigger chance that your buprenorphine doesn't stop working too soon.
