We opened a new box of Lucky Charms from here this morning, and soon after finishing her cereal, she started violently shaking, had severe nausea, and swelling throat. Very scary and we almost took her to the hospital, but she is much better now. She woke up... See More perfectly healthy, dancing around the house. She has never reacted like this to anything before. #luckycharms #costco #generalmills | Symptoms: Nausea, Vomiting, Swelling, Shaking See Less
