Oh my gosh. We have had the same symptoms here. I think it was the flu because my mom got it too.
I had one day of vomiting and diarhrea of #2 (at the same time as vomiting). not a pretty sight. My stomach hurted a lot and my head was hot. I slept all day on Thursday and still wasn't better the next day 100%.
I think something is going around...
I do hope you feel better soon.
