My 2cents. I'm a fairly recent user of Kratom. I have a serious neuromuscular illness that has made pain my constant companion for going on 30 years. I've been on hydrocodone for the better part of ten years (prescribed at 10/325 4x a day). My tolerance to hydro is to the point where I wanted to take a break. I bought Kratom as strictly a WD mitigation aid. Surprise surprise! It's a very effective analgesic in its own right. Now, it's quite probable that I'm in the "honeymoon phase" of this relationship. I've only been using Kratom for 6 weeks. That said, it's a sweet little pain reliever. It does very little for me in the "euphoria department," but neither does it slow me down. And yes, it mostly puts hydro WD to bed. It really does more for my pain than TWO of my hydros, and lasts twice as long.
