I managed to taper off down to a manageable level (about half a coffee spoon every 5 hours), but going beyond that was impossible without feeling the withdrawal effect pretty much full force, I decided it was best to bite the bullet and stop cold turkey.
Extremely cold feeling coming from inside on a very hot day, awful restlessness (which made it impossible to sleep more than 2 or 3 hours a night for the first week, before I had to give up and go on sick leave), the most intense feeling of being devoid of energy both physically and psychologically, and pretty much all the symptoms of a strong cold. The extreme sleepiness and impossibility to fall asleep because of the restlessness is one of the most frustrating combos I've ever experienced, but I'm sure that's all too familiar to opioids users.
If you're trying to kick off an existing opioid addiction (or maybe have some sort of pain where the usual pain meds channel are not available?), this might make it more manageable I'm sure, but all the analogies to coffee or tea as "Just a thing you can take if you wanna calm down a bit" can be extremely dangerous to people that have essentially no need for it, and particularly people with an addictive behavior.
I have personally seen several friends kick regular pill habits with kratom and they got off it OK. We should discuss the downsides but from what I've seen the folks with kratom problems just took way too much(as addicts will do, I guess).
It really is strange the way many people have negligible or no withdrawal symptoms, and others report that they do. One theory is that you didn't just take kratom - there are known cases of it being sold mixed with synthetic opioids (o-des-tramadol is one such, from memory).
I fully accept that different people have different experiences coming off of a drug. I should have mentioned in my case that was about 8 months of daily use, although the withdrawal symptoms shown themselves very quickly (less than a month after I started taking it regularly).
I personally feel sluggish the first days if I stop coffee for a while, but even after drinking coffee every day for a comparable period of time, I don't instantly feel the withdrawal creep up on me as soon as caffeine (mostly) leaves my bloodstream.
For added context, at the peak of my consumption I would take about a teaspoon every 4-5 hours (consistently as this was the time it took to feel the cold symptoms again) through tossing and washing (just swallowing it down with some water). I've no experience with Kratom pills and no amount of sugar can possibly overcome the intense bitterness of Kratom tea at that dosage (and I like bitter).
I wonder if perhaps there is some kind of genetic factor.. it's very strange in any case.
If you know this about yourself, maybe don't start taking opioids. There is certainly a subset of the population who, like yourself, seem to have addictive personalities regardless of the substance. That shouldn't really inform policy on any particular substance.
This isn't me defending myself as not having an addictive personality, I'm sure I do, but I managed to stop smoking, coffee, alcohol and marijuana, some of those at the same time. Addiction is a problem that still plagues pretty much every country but even then I wouldn't say I'm necessarily in favor of banning kratom.
My original comment was only to point out that it clearly isn't as benign as a wide range of people make it seem. Of course if you go on the kratom subreddit you'll see addicts praising its benefits and rationalizing all sort of life improvements in the short term, as well as legitimate "success" stories, but most people who kicked the addiction don't repeatedly frequent and post there. I'd think this massive bias to be fairly obvious, but it might be worth repeating (this isn't aimed at your comment specifically).
I'm certainly not convinced it does cause dependence, especially not to the same degree as most opioids. As a sample size of 1, I was always able to stop taking kratom without suffering any kind of withdrawal, and there are plenty of other similar anecdotes on reddit (to be fair, there are plenty that do talk of cold-like symptoms when stopping it)
