I have no clue, either. Perhaps it was just a fluke.
Some garlic cloves are very different from others—-like very hot.
But, it sounds like you had nothing special.
I have no idea of what may have happened, it has never affected me that way.

Not that I know of. 

Also, no clue about strength. Just a regular garlic from grocery store

Was it the super strong version or a milder version.
One will put burns into your mouth and the other just tastes good.
Are you allergic to it? Or did you eat something that reacted to it?
