I am hoping someone can help me, after giving up tea and coffee a few years ago I recently started drinking coffee again. I have noticed that every time I drink a latte i get a seriously bad stomach ache that can last from 8-20 hours. The pattern I have detected seems to be that if I have a black coffee and add milk then I seem to be fine, it is only when I have lattes, could this be something to do with the milk being warmed/boiled before it is poured in to the coffee, or perhaps it is just because there is more milk in a latte than when I add it to a black coffee (although i do make it very milky). At first I thought it might be a simple milk allergy but the fact that I don't get ill when i have milk on my cerial or when I add it cold in to a coffee or in other dairy food, I just don't know, it is just every time I drink a latte.
Can anyone give me any ideas on why this is happening
Thanks
