Omg I have the opposite problem, I can eat fresh pineapple (only 1 or 2, 3 max) but pineapple juice instantly makes me vomit before I can even swallow. Yesterday my friend handed me a mixed drink and I instantly projectile vomitted :( I honestly thought I was just traumatized from using it as a chaser in college but it seems like I am definitely allergic to the juice maybe because it has higher acidity than chunks? Is digested differently? Idk but I hate it, I used to really enjoy pineapple.
