Nodding out permanently is a definite danger, but choking on one's own vomit is perhaps a greater danger if large amounts of alcohol & benzos are consumed. I don't know if you have a therapist, or not, but I'd discuss this issue with him/her. In my experience, hospitalization isn't very helpful, but if you think you might repeat this pattern, I'd take the risk of hashing out what happened. Stay with us & post more if you want the "noise to stop."
