I'll start by saying I'm a coffee-lover, but I'm also pretty good at keeping my passion under control. Once in a while, though, I like to stop at one of those local drive-through coffee houses on my way home from school. I love lattes, granitas, chais, steamers, and pretty much anything, hot or cold.
About a year ago, I came home after drinking a hot latte and suddenly felt sick, as though I needed to vomit, coupled with the urge to use the restroom. I assumed I was just car sick (I get motion sickness very easily) and thought nothing of it. But ever since, about one-third of the time I drink coffee in the car I experience symptoms of nausea, weakness, lightheadedness, and symptoms very consistent with those of dumping syndrome as I always have to use the restroom immediately after finishing my drink.
It sounds like it may be lactose intolerance, but here's the catch: it doesn't always happen. The only times I've noticed it is when I'm a) in the car, and b) there's a substantial amount of milk in the drink in question, and c) the milk is hot or warm. Never does this happen with cold milk--ALWAYS hot.
For another thing, I've never experienced any problems with milk-based products anywhere else. I can eat an entire bowl of fettuchini alfredo, the richest ***m chowder, or a carton of ice cream and feel as dandy as can be. But if I drink hot milk in a moving vehicle, I'm doomed.
Could this be a milk allergy or just a weird complication of motion sickness? If it helps, I am a healthy 17-year-old female with no other allergies.
Thank you for your time. I would like to solve this problem as soon as possible and eliminate any concerns I might have about lactose intolerance.
