Just from my experience, careful, I had to cut 10g of my kratom daily dose, which was over 40g a day at the time, I felt pissed off, obsessive ruminating about the past. The cut helped a bit. I've heard others get this effect, look it up on here, it's called "kranger" or "krage" I also hear opioids cause it, and there is an opioid element of kratom. I'm now weaning, and on 22.5g I'd say keep your dose low.
