It's not as much about the dose you take as it is how often. I take much higher a dose than you normally, 500 is on the low end for me, but thats enough to cause wd issues after a week of use. You really shouldnt push it more than 2x a week max. Trust me. I deal with kratom as well and have an issue with that too, as did a major amount of people on r/quittingphenibut. A lot of people there took it for kratom wd and found they had hell to pay for even 4 or 5 days of consistent use. It isn't something to mess around with dude. Trust me on that. The wd from kratom aren't fun, but this is like that x50. Most people don't really understand how a 36 hour long half life can effect them, since most drugs don't act that long. This means after 3 full days you still have 25% of it in your system. With 500mg I wouldn't push it more than 2x a week IF you're going to constantly use, or 3x is you're going to take a week or 2 break after. Most people would say that's too much, but I've had no issues as long as I take a couple week break after. Even at 2x a week, you're likely to start developing a very slight neurochemical dependence within 1-3 months. Plenty of people on here have had that exact thing happen to them
