The last few days have been a bit difficult because my wife Lynette had a very bad flareup of her celiac disease. She cannot tolerate wheat and some other grains.
Non-stop nausea, vomiting, diarrhea and painful abdomen went on for over a day. She became weak and dehydrated. Even now, the day after it's difficult to get her to drink fluids. Chicken soup, green tea and ginger ale are all I can get her to take; that and anti-diarrhea and nausea medication.
I think the "gluten free" pizza at Ledos restaurant was the cause. On the menu it was listed as gluten free with a warning that they could not guaranty any cross contamination. I ate some and I am fine so it was not food poisoning.
Here's a video which explains it better. The sound is a little too low so you'll have to turn up the volume.
