you ever get a headache so bad you feel like throwing up?

Yes, just like you when i wear glasses lol. But not to that degree

Sounds like you have a migraine

Dark room and cold compress might help, along with extra strength Tylenol

I have.

I haven't had a headache this century - or way before that. It's a mystery to me because I've been hungover hundreds of times but... no headaches.

Not from wearing glasses.

not recently.

Sounds like death
