Crazy question. Can the evacuation of my boyfriend cause me to be sick? Flu like symptoms. I don t drink, but he does. The night before he had gotten quite intoxicanted and his hangover was horrible. 24+ later we had intercourse. About an hour passed and I had chills, sweats, was shaky, severe cramps and had diarrhea. I had also been eating an organic nutrition bar, which I hadn t had previously. My first thought was that I could not have a food reaction that fast. So, I thought the only other thing which I could have obsorbed was what him and I had just done. I m probably way off. Enlighten me, please.
