You gotta practice and feel kratom out, work with it to find what works, takes some time and a personal learning curve. Biggest problems are noob taking too much, get sick or dysphoric, or opiate withdrawlers not taking enough, also not weaning off the hardcore so they get almost no effect, wait till your in withdrawal to take it.
2 times a day max spread apart for fun. If you got pain or withdrawing do what you need to do.
