How bad are Anti-freeze fumes for you?

I have a small leak in my heater core, but a radiator leak solution has managed to stop it, I think.
Nonetheless, I’ve been breathing sweet antifreeze fumes for the past few months.

How bad is that? Is it worse than the acid I dropped back in high school?

Ethylene glycol fumes are not as bad or you as acid fumes. Prolonged breathing can cause dizzy spells. Here’s the material safety data sheet. It lists all the known health effect. If I were you, I wouldn’t get too worked up over this.

Hmmm…
It could just be me but I think dizzy spells while driving are pretty bad

They sound pretty bad to me.
Perhaps that’s why I have a persistent cough.

Oh, I’m doomed…
