My personal experiences with Kratom have not been anything great. I found it to be rather expensive at the smoke shop I bought it from. It was about $30 for maybe 20 capsules. I've gotten it 4 separate times; the first time I got a really dirty, sickly high and I threw up. It was strong though.
Second time, I tried to take less, felt NOTHING. so I took the rest, threw up, never felt a thing.
Third time I bought the most expensive one they had, the guy told me to start with 5 pills since i'm a small girl (120 lbs). So I said Fuck that, and I took about 10, then I felt mild euphoria, about an hour later the euphoria started to leave so I took the other 10, then I threw up, never got any stronger.
Fourth time, I bout a small liquid for $15. It comes in a small 5 hour energy type bottle, drank it all on an empty stomach. Never felt a thing, and didn't throw up this time.
I give Kratom 2 out of 10 stars. By the way, I had no opiate tolerance at this time.
