My husband had it.
We never bought meat to use at home anyways, so in that aspect nothing really changed.
However it was kinda cumbersome when invited by other people, especially since we live in a backwards place where people consume meat daily. E.g. grandmas kept cooking red meat despite me trying to explain it multiple times and getting offended when he didn’t eat it.
Oftentimes my husband would just eat a bit of it anyways and then spend the evening in the toilet throwing up, just to avoid the strange drama that telling people you can’t eat meat causes.
That’s also how we figured out it goes away, since the doctor made it sound like it would be permanent. But eating the bit started to get less bad and then eventually stopped causing any issues. Now he can eat anything people serve again, which is saving us a lot of headache and drama.
We’re not even in the US. We assume he got it from a trip to Mexico because he has never been to North America at all.
