^Double Agree. Get some Kratom or even some Full Spectrum Tincture (FST) if you are looking for a nice opiate feeling. It's legal too! (Mostly, check your local laws, it's legal in almost every US state).
Once you go down the path of H, say goodbye to Oxy, Kratom, Vikes or anything else that isn't as strong as H. With a serious H habit, all that the other painkillers will do is provide some relief from WD for the days that you can't score. You won't be able to get high, only well. And eventually it gets that way with the H itself. Such as the path of heroin addiction. Is this going to happen to you? Maybe. Maybe not. It's highly probable. Not written in stone. But you have a pretty high chance of getting hooked, especially if you enjoy the experience.
