Barry I hope your mom gets to feeling better soon.

Years ago I ate some clam chowder at the Red Lobster a chain here in the states. Later that afternoon while doing chores I felt cold, clammy, & really weak. Luckily I threw the chowder up but did not feel good for over a week after & my appetite was like your moms. I lived on toast, squirt, & crackers for awhile after that. Ever since that I don't eat soup at any restaurants anymore. It sounds like you both had food poisoning & I know that is what I had that time.
