*First post to bluelight, hopefully plenty more to come*
I'd like to add my own experiences for the above posters, and because I have gotten so much from bluelight I felt I needed to add something for others going through similar experiences.
Kratom does seem like a very good choice for acute suboxone withdrawal. I have used it in the past and had excellent results. Currently, I was down to less than a mg and skipping days of a relatively short stint (5 months) of suboxone use. At this dose and frequency of consumption, kratom will hold me through til at least 6 hours, and dosing only needs to be done on a 2x daily basis, once in the am (I believe this to be essential, not only since right as I wake up I have to prepare for work) and this dose gets me almost all the way through my shift. The second dose I take is at night, around 7, to allow me to get to sleep. Now, I understand that my relatively short duration of use and relatively low daily dosage make my story and the OPs very different, but considering bupes ceiling effect they may not be all that different. Perhaps the biggest difference is that I would be able to make it through unaided (as I have in the past).
A couple points that I have found important to kratom-assisted bupe detox is try to space the doses apart as much as possible, and try to limit the dose. This is not to add to your suffering, but I've noticed that kratom seems to lose some of its effectiveness with multiple dosing and dosing done too soon after one another.
The second, and I may receive opposing view points on this, is try to obtain some gabapentin. One of the major differences between my kratom assisted detox this time is the addition of gabapentin (originally added since I'm going through phenibut wds at the same time). If anyone is reading this, please know that IME 300mg of gabapentin will stop a 2+g a day phenibut dependence in its tracks and provide relief in well over 7 hour intervals. I will never attempt another phenibut wd without gabapentin again.
The gabapentin has reduced the severity of the wds immensely (as felt in the interdose wds experienced between kratom doses), and requires a time greater than the timeframe of acute suboxone withdrawal to develop a dependency issue, if one were to arise. In addition, it is quite easy to obtain from a dr, being as it is unscheduled.
Just my experience.
