Bought a new jar of peanut butter at Plano HEB (Central Market) was the HEB brand of unsalted, chopped peanuts, butter. Ate a good-sized portion about 7PM. Woke at 2AM with acid reflex condition. From 2:45 - 6AM terrible vomiting and watery diarrhea. Wife and I ate exactly the same things, except only I had the peanut butter. She did not become ill.
