I used to do this a lot, not necessrily to check out for a bit, although that was probably partly it. My main motivation for it though was knowing that I could be doing long term damage to my organs and ultimately could die.

I don’t tend to do it much now, although if I’m stressed and can’t SI by cutting which is what I do more, then I tend to reach for the pills instead. Not to kill myself, just to calm things a bit. I don’t know how it helps but somehow it seems to.
