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:
