I have been taking 12gm per day since February 2017. I had S1-L4 spinal decompression surgery in September 2015 and have suffered post-surgical back pain ever since. For most of 2016 I was taking 20 mg per day oxycodone. I found kratom and took myself off the oxycodone, and have been that way since. Without kratom I will be forced into taking the opiods again.
