My boyfriend purchased items from a gas station and we got home didn't hear anything about anything wrong with him till like an hour after we had got home..said he was feeling nauseated and went to lay down and asked me to bring him our trash can just in case... a few minutes later he threw up. But just one item he purchased everything else he purchased didn't come up. And I found out it was a butterfinger peanut butter candy bar with chocolate coating. Is this any sign of low or high blood sugar he didn't tell me anything else was bothering him just nauseated. Thank you have a good day.
