I ate a few grapes yesterday, like maybe 5 or 6. The first one tasted really horrible as if it was bad or just a really odd taste. The rest I just washed again and they seemed ok. I then didn't feel like eating dinner last night but didn't really know why. Then suddenly from no where I started vomiting. I hardly made it to the bathroom it was so sudden, but it was just once. Then I felt better. But today I'm having vertigo for a few seconds at a time, randomly. Do you guys think the grapes were bad or maybe I just picked up a virus? My kids had eaten some grapes too. My 3 y/o spit one out saying it taste gross. But he ate more and even today they ate some. They all seem fine. Should I throw the grapes out? They don't look bad or seem bad.
