I find it interesting that so many people have this experience because I've always been the total opposite. I don't know what dose you dropped off at, but if I've been taking around 1mg 2xday or less, I've always been able to get high without having to wait more then a couple hours. I even shot up 30mg of oxycodone once and was destroyed. Maybe it's because I've almost always used IV when going back to other opiates, although, with kratom, I found that I could feel the effects on top of the Buprenorphine as well, even in lower dosages like 4g, though that might be caused by kratom's high binding affinity.
However I will say that the effects of the high aren't as euphoric as they used to be, and I think buprenorphine is somewhat responsible for that. I would always nod out, but barely any euphoria. I've switched so many times back and forth between methadone, Bupe and heroin that asides from myself I don't know what to blame.
[MENTION=286519]tightlywound[/MENTION], theirs a possibility I suppose, if you shoot a high dosage like 16mg that the naloxone might have some effect, but the fact that you felt nothing and didn't feel withdrawals makes me think that it doesn't. There are many reasons that one day a dose might hit you hard and another day it might do nothing (explaining why the 'text gave you a little buzz). However most people don't IV nearly that much Buprenorphine, it's really only worth shooting IMO when you lower your tolerance to 2mg IV a day, and start doing microgram shots. That's when you can get something of a buzz out of it. IV Buprenorphine is so much stronger than sublingual, it used to be hard for me to wrap my head around it, but 30% bioavailability is almost an exact measure to equate IV-SL dosages (for example 1mg SL=.3mg IV). Back when I was really into it I remember getting the most out of my shots at around a 150-200mcg range. I never found IV buprenorphine to be anything to write home to mom about, but at those low dose shots I would occasionally even get a dope taste in my mouth.
