I'm just curious if what im experiencing is a normal food aversion or possibly something else going on.

So its been made very clear i can't eat bananas. Its DD's breakfast most days and most days she will only eat half so instead of waste i would usually finish it off for her. But recently ive noticed that maybe 15 mins later i develop a headache, if i already have one which these days is very common it gets worse and over the course of maybe an hour it gets worse and worse to the point of i am unable to stand without feeling my head is about to explode. I try different things to try ease the pain but eventually i start to feel nauseas and then i have to bolt. The vomiting is very severe basically i open my mouth and it just explodes out. I then spend 20 mins dry heaving and bringing up bile until i can no longer do anything.

The same goes for beef. Other meats i am fine, some make me a bit queasy and i might have a bit of a spew but nothing compared to what happens when i eat bananas or beef.

For obvious reasons i avoid them both, now.
