My daughter and I have discussed using the octo to puke in if we get nauseated underwater. Fortunately haven't had the occasion to try it, but gives us extra incentive not to go low on air!
This isn't from any personal experience, but I'd say, "don't"...
1) If you are feeling bad, you are probably not in top form as far as thinking and coordination, don't make life complicated.
2) From what I've read, most people reflexively gasp for air after vomiting. That's OK if you have a reg in your mouth. If you think, "oh, I think I'm going to ralph, better switch regs," get the primary out of your mouth and suddenly can't hold it any more...bad day.
Just clean it off really really well, after.:yuck:
