kbombI totally understand. I've had my share of presentations in school and I always got a little nervous beforehand. And you're right, it sucks to be LAST. You know what I always found though? I would get rumbles and cramps for about an hour or two before presentations and exams. Sometimes I would even have to go to the bathroom several times. But I've always found that once the test or whatever gets underway, I start feeling more relaxed, and usually I get terrible hunger pains too. This is because I don't eat before. In my 5 years of being in university, I've had the big D before these major stress events, but I've never had to run to the bathroom during them.But if you are worried, take a couple of Immodiums just to be safe, I find the new Immodium Advanced tablets really help with the crampy feeling.
