weird experience

Recently did a fat bump of crushed crystal. Come up was good but instantly started to feel increasingly nauseous. Dizziness set on as per usual then I started to feel very warm and started sweating profusely. After a couple minutes I rushed to the bathroom and started vomiting and then the diarrhea set in. Felt a little better after that but I was still confused as this has never happened to me before. Anyone experiences this?
