Hmm... I can't be sure it was a tummy bug. Because there are many reasons why people v*. I've given up worrying about emet until I feel sick. When I feel sick, I whip out the ginger tea and relax. Most of the time it's from anxiety.
The last time I was physically ill was when i had tonsillitis. I have only v* with that. Never had a stomach bug before. the other tiems i've been sick was when I had bad panic attacks where I did be sick. :/
