Every morning my freshman year in high school, I felt sick. I would miss a lot of first period class & summer swim workouts as a consequence. My mother and I could not figure out what was wrong.
Every day shortly after breakfast, I would get nauseous and have to lie down. One morning, I told my swim coach, who was frustrated with me missing so many workouts, I had “morning sickness.” At the time I was 14 and clueless to the usual context in which that phrase in used. Mom was mortified. I had to clarify to coach that I was not actually with child, and then it was off to the doctor, who confirmed I was likely lactose intolerant, so I stayed off dairy.
