ya, that sounds like a form of self-harm. because of the effects that it could do to your organs. Either way, it's still not a good thing to do. Take it from someone who has SI'ed a different way then most, it's not good no matter what you do. But try and stay healthy, (you know food helps the immune system, as well as sleep) If you want to be healthy you'll stop.... which takes as much strenght as staying up all night. (and for some my signature helps)
