I have thought about that myself, I only worry, with my addictive and impulsive personality I would just relapse on the dope, and never get off that or the subs! it would probably help to do something like this, or you could do dope, then slowly transition to weaker opioids than heroin like oxy or hydro, for a bit, and just skip the subs, then slowly wean yourself off of it all, maybe use a little loperamide to get through the worst of the dope/opiate withdrawls after.. BUT you would have to REALLY want it, and be strong enough to stop! I think it would be hard either way, actually I know it would, I have been jumping from bupe to dope, and back to bupe, going up and down, and up and down on my sub dose, whenever I start feeling like I want to go grab so dope... I go up on my sub a little bit, my doctor, has no problem doing that. Bupe is a real mind fuck huh? I originally got on it 5 years ago, thinking it would just be a couple months, and I could just stop everything... but it never happened. it is different for everyone, I am really fucked, because I actually love the feeling I get from subutex! seriously, I do subs, IV, we have chatted about this before, and feel as good as I would from some of the full agonists out there! its crazy! Last time I did a few oxys when I went off my subs for a weekend, I fucking regretted it big time! with the oxy, I waited like my normal 12-14 hrs which always has worked when taking low dose bupe then transitioning to full agonists and feeling the full effects with no blocking from the bupe, after taking only 1mg early that morning then doing like 90 or 120 mg of oxy, I was pissed I even got the oxy! it sucked! I would've rather just saved my money, and done my subs! because I love how long they last, compared to stuff like oxy IRs.. I don't think, unless they are free, I will ever do another oxy again.. heroin, that's different, I always feel amazing, and then don't want to go back to my subs! But yea, I am rambling... you could probably get away with this, without even going back to the subs at all.. I think they would prolong the withdrawl, even in super small doses.. but idk.. it would take tons of will power to not want more dope.. for me at least..
