Went out for Mothers Day dinner to an Italian restaurant. Ordered the cioppino (seafood) dinner. About half way thru, started feeling sick in stomach. Thought black coffee would settle stomach down. Didn't work. Drove home, took a couple antacid (Tums) pills, that seemed to settle stomach down. About 11pm, started having stomach cramp and diarrhea. This continued until midnight when I finally went to bed. No further discomfort during the night. Next morning, I checked weight on home scale. No change since previous day.
