Yeah, I completeley agree. If you were going to be sick, it would have happend already. Try not to let this evil phobia take over your day with your friend. I know thats easier to say than do, most people do not wake up feeling sick, and get sick that night if they have a bug. It usually hits them very quick, you get nauseaus and a few hours later your are sick. You don't have a tummy bug, it's probably just a nervous stomach.
