This sounds like a joke/troll thread. But to be clear to the OP in case they're not joking, and to anyone else reading this:
Methadone is FAR worse to come off of than kratom. 1 tablespoon of kratom is about 6 grams. 6 grams once per day is VERY low, and you could probably just jump off that with little to no suffering. Methadone is way overkill, basically you're using a stick of dynamite to blow up a cardboard box, instead of just stomping on it. You're going to end up stuck on one of the most powerful opioids, which makes kratom withdrawal look like a stroll in the park on a slightly cloudy day. Methadone withdrawal can linger on for a month and is much, much more painful.
I wouldn't even recommend methadone to come off of 100 grams per day of kratom.
Seriously you will regret this decision so much if you do it. if you're getting withdrawal from kratom, get some clonidine and gabapentin from the doctor and take gabapentin for 5 days and you'll not feel any withdrawal, then stop the gabapentin and you'll be 100% fine. Don't take the gabapentin for longer than a week or you can develop dependence on it. If you can't get gabapentin, see if you can get clonidine, just that might do the job. if you can't get either, or if clonidine doesn't help you much, get some black seed oil like
@negrogesic suggested, it helps a lot with mild opiate withdrawal and is not addictive, and you can buy it on amazon.
EDIT: 12 gauge on a mosquito is a much better analogy
But really, typically might try to use kratom to come off methadone, not the other way around.
