This can easily be different from person to person and often dependent on how big your habit is and how long you've been feeding those receptors. I had a pretty good habit that lasted 5 yrs, but anything that's daily and between a half year to a year+ I'd say is looking at needing a significant break(no shortcuts, several months at least) if you plan on doing ANY tinkering again in the future without really quick return on dependency. I know your brain is entertaining these options anyways so I shall inform. I would have to take 150mg oxy to have any real fun, so that got stupid and I did the typical jump to heroin. The idea of tinkering around and still making headway on your recovery is pretty close to impossible for me, and I wouldn't plan on much of a difference for yourself. I found out the hard way after about 5 attempts of caving like 1 or 2 extra days each try. It's so hard when you know you can feel great again from a dose you start craving it. But it's so not worth erasing all the previous days. Unfortunately it only takes one mental hiccup to relapse if the medicine is available, so I'd suggest getting rid of that some way where you know for sure it's not available to you. It was worth it in more than one way not having to worry each day about how to stay well. My habit is big enough that I can't go back to opiates for quite a while. It's like my receptors never forget what to do with opiates if they see them. Discards the fun and embraces the withdrawal, even though it's at a manageable level now. If you want to live risky and play the never ending game I can give you the secret time range: 2 weeks(if no sub/methadone dependency). You can stay off 2 weeks but you won't be able to stay independent for long if you go right back to using daily again, I mean within a week if not a few days you can easily be back at full blown withdrawal if you've been doing opiates for any kind of significant time. Quit for a couple months with the mindset of quitting for good would be your best chance at sticking to some sort of sobriety. Some people just have to fail a couple times. I find it's most common with opiates so you need to take every measure. Spend time on planning out your withdrawal so you will be serious about it. Pick the right time, setting, set up the right stash of meds: Loperamide, Clonodine(script req), weed, B vitamins, etc.
On the lope; Take 20-40mg each dose for only 5 days, seems like a lot but trust me it's not, people can take hundreds of mg's, but it's not advised and you need at-least 15-20 to get the relief. Between clonodine & Imodium together, you would probably get close to 90% withdrawal relief. These are legit & you wouldn't need much of the clonodine at your tolerance(probably just 1mg at morning/night). No fear even if getting the clonodine isn't viable, the Imodium can relieve probably 50% by itself and help with the shits. If getting clon isn't happening, then try to make smoking weed an option if it isn't already. The Imodium is the must have since it's multi purpose and easily available. whenever going through a real withdrawal. I will never say it's a cake walk, but with all three drugs(clon, imodium, weed) it's about as close as you can get.
quick answers:
-Yes most likely it will bring back atleast a portion of the withdrawal depending how long you've been taking/how long your receptors have been used to it. In my case, that would bring back almost 100% of withdrawal.
-For habits smaller than 80mg oxy daily, I really don't recommend opiates to get off other opiates. If you're into prolonging the whole process it can work. But if the option of just going CT is available just do it, it's not so hard with the meds I listed and your tolerance. Your receptors really need a break.
(If no maintenance drug dependency like sub or methadone, the withdrawal is only 4-6 days)
You got lucky and caught me when I smoked and I actually dont feel like shit for once, so I felt kind enough to give you pretty much all the most important information you need to know to quit. I've already done all the trial and error as far as finding a plan for recreational use once you've become an ex-addict and it's really close to impossible because you're expectations will often exceed your results, especially the more you try. Even at your tolerance, if you've been hitting your receptors for a year+, it's like they just remember what to do with opiates whenever they see them. Trust me, just do the CT. You're at a crossroads in my opinion. My tolerance shot up like a rocket and became more of a burden than an enjoyment when I hit the mark of needing 40+mg to get a good high. You're pretty close, don't let it get higher.
