Chocolate chip brownies About 10 pm last night I baked some regular chocolate chip brownies and added some tollhouse semi sweet morsels to the mix. Let them cool and ate two pieces of brownies. I had to drop my friend off at home who also ate 2 and experienced some stomach upsetting but no nausea. I got home around 4 am and was woken up around 7 from my stomach turning. I felt like I needed to use the restroom but I couldn’t hold back. I threw up brown/tanish. I didn’t eat a lot prior to eating them, I had some eggs that morning followed with a hamburger helper Mac and cheese later on that evening about 2 hours prior to the brownies.
