It all depends on how much suboxone you're taking and how long you've been taking it for. IE: Have you ever hit the ceiling, etc. I find, that if you take suboxone in consecutive days as to hit that 32mg ceiling, the time you have to wait to get high off full agonists GREATLY increases.
I've been on suboxone for 6 months now, but I've started fucking around again with opiates over the course of the past month. I've still been able to get plenty high off both oxycodone and heroin each time, and I do not ever go through withdrawals at all, based on how I time my suboxone dosing and opiate dosing. I technically, am supposed to be taking 8mg suboxone per day, but I do not. I take 4mg at most, usually 2mg. Here's what I do..
Considering I only take 2mg of sub 99% of the time, it's really not an incredible amount of suboxone tying up your receptors. A high enough dose of a good opiate will blast through 75% of it. If I plan on doing oxycodone, I will 24 hours. Now, that first opiate dose I usually make a pretty hefty one. Reason being is, I believe by doing so, it knocks off a greater percentage of bupe that's attached to the receptors. Resulting in more receptors being completely freed up for the next time I dose an opiate. I say this because I "think" that once a receptor is freed of suboxone, it won't wait until the opiate has been displaced and simply walk back in, for lack of better term. I can be wrong about that. I also have a very fast metabolism, am very skinny because of it. Due to that, I feel the half life of sub for me is decreased slightly. I will then take my opiates for a couple days, with the high getting better each time until I'm getting 100% of the desired effects. I will then take a break for any number of reasons, and will take just 2mg sub 12-14 hours after my last opiate. Whether it's oxycodone, or dope. Intranasal and iv. Only need 12-14 hours to avoid PWD, for me anyway. I believe this is again due to my metabolism. This is not the same for everyone.
Because I go back and forth between opiates and suboxone, I am never letting myself hit the ceiling level of suboxone, which I feel would result in a much longer wait time in order to feel full agonists. Also, I can get FULLY 100% high 8 hours after a 2mg dose of suboxone, if I shoot dope. It completely obliterates whatever suboxone in my system. For example, the other night I got so high from a .1 of amazing dope that I threw up for the first time in 2 years of heavy opiate use, and I STILL had suboxone in my system. I took the shot not even 8 hours after my sub.
I don't recommend this to anyone. It's really a painless way to be an addict. I never withdrawal. I can get high whenever I want, and feel normal whenever I want. I don't suggest anyone "cheat" the system like I do, because it really makes it too easy. I'm moving away soon, so I will be going back on my suboxone full time, and I will be kicking my dosage back up to 8mg/day as to stop the inevitable cravings. With the 2mg I take now, I still get cravings even under the influence of suboxone, although minor. The main thing is I'm never experiencing physical withdrawal symptoms, which makes shit really easy and too good.
