If you interested in just feeling normal it could work. For me at least it work great. I mean, that i wasn't addicted to opioid before taking Kratom, but now I'm addicted to Kratom and dosing it every 4-6h makes me feel good and fresh all the time, after 4-5h after last dose(on the low doses, 5g) i start feeling tired, after 12h i have actually strong withdrawal, that makes me almost not possible to make anything( beside laying in bad andbeing sick.i can't even sleep cuz i keep moving my legs 2
