Obviously some prescription drugs, hard drugs, alcohol, CBD, ashwandgha etc, could all well help to varying degrees. But you'll probably find that the real courage comes from within yourself, when you're truly ready, and have accepted your fate. Sounds cheesy, but it's true, I can vouch for it. The body will always put up some kind of fight in the moment (if it can), but people with an iron will overcome any SI. May I ask, is complete hanging your method (based on profile pic)?
