I haven't seen any peer-reviewed literature talking about this particular aspect of kratom or mitragynine, but if you look at Erowid or the kratom subreddit you will find hundreds if not thousands of people saying the same thing. Anecdotal, I know, but still.

Once it's rushed into Schedule I, good luck getting it.

I guess you could always take a trip to Thailand...

...where it literally grows on trees.

Anecdote: I had a far-too-large dose produce obvious precipitated withdrawal – intense sneezing, elevated body temperature, and nausea. It resolved in a few hours. The plant contains a mix of agonists and antagonists IIRC, and this seemed to be protective. I don't use the stuff anymore, but it certainly didn't ruin (or even really damage) my life.
