I always hesitate to say shit like this, because I'm worried people will overdo it, but the first couple times I did kratom I didn;t get nearly as on as I should have because I was trying to take it slow--which is ALWAYS good for something unknown. But really, if you;re not feeling anything, you should up the dose, and keep going (like a g every half hour) until you're faded. You might need 15 grams to get off.
