Hi! That does sounds like a typical allergy to aspirins, though you can test it without having to suffer those I'll effects. The way to confirm if you're allergic is through a skin test, basically they inject a small amount diluted on solution, and if you're allergic you'll get a small rash on the inoculated area, no need to take them orally, so don't worry about vomiting again 😂
And as for my girlfriend, I usually send her the link to my articles, but I think she won't get to read this one hahahahaha.
Hahahaha.. Lucky for you with the girlfriend ☕
