Oreo
Wow, that’s a severe reaction indeed. Am guessing you’ve tried skimmed oat or other milks as well?
Oreo Oat milk looks like milk. I think I have this instinctive reaction, which is quite seperate from how I physically react to milk because my primary school education, and later a prolonged hospital stay was made hideous by people trying to make me drink my daily free bottle of free milk. Food intolerances, especially mild ones were just not understood then.
School milk was often stood on the radiator to warm it through, which made it even more revolting to drink. I became adept at taking my milk and then disposing it somewhere undrunk, but sitting at the table during school lunches, one had no escape and in hospital,.
One nurse discovered that I would casually wander down the end of the wardwith my midmorning milky drink and tip it out of the window (it was a ground floor ward) and would sit over me. In the end, the Ward Sister discovered what was happening and told this nurse in no uncertain terms that if I did not like milk, I should not be made to drink it. I was 13 by then. Instead I had a cup of tea from the nurses teapot. I suspect that the Ward Sister shared my aversion to milk.
