Do boats usually have a bathroom?
Basic question - may seem odd but scenario happened last week
Interested to hear what advanced divers/dm/instructors have to say
Diver in group has attack of Montezumas revenge on first dive with group of people unknown to him and a DM/Dive Leader. Twenty minutes into 50 - 70 foot dive he knows he has to *go* and won't make it to safety stop or boat and has to *go* underwater
What is the protocol/etiquette How do you slip away without alarming Dive Leader or do you just let it all hang loose and hang the embarassment?
Sorry if this is a Q that raises eyebrows or churns tummies but this is/was a real scenario
Here's a more civilized way. My friend does this a lot. I think he'd rather go underwater than in a bathroom. That's his backplate webbing below his butt....not what it looks like.

My father in law tried that maneuver. The ..uhm.."hammer", floated up inside his rash guard between the nylon and his back. He did not realize it until he got back on the boat.

Along the same lines, but opposite end, what do you do if you feel nauseous and have to throw up? Forgive me for asking such a basic question, as I haven't yet taken any classes. Have any advanced divers thrown up underwater and actually survived?
Puke in yer reg....errr...octo.
It works just fine.
Chug
Did that a few times.
Yes you can vomit through your regulator at depth, it is one of the topics covered in basic scuba class.
