MrJerseyGuy,
This is just what I read from someone that was pretty knowledgeable on the subject. The more you ingest the more bacteria your body has to deal with and they harder it could be on you. Your body can handle a small amount of alcohol but too much and you get alcohol poisoning. My information is just what I was told. Doctors opinions are going to vary as well. One doctor tells you one thing while another tells you something different. I have never heard of anyone dying from it but then people die from flu shots. If your not the healthiest person then maybe it's not a good idea for you.
It would seem that some people are very into this and they dont seem to be dropping like flies so who knows. If your totally into this kind of thing then maybe you should do a lot of research before trying it. A lot of things in the bdsm can be very dangerous.....so, there you go.
