bass note hangover?

Worked on one of my “crazy new recording ideas” that are top top secret so I can’t explain it so it’s not stolen before I’m finished.   But here’s the thing I’d like to warn you about, even at low volume exposure to bass notes that are close enough together to “beat” for 4.5 hours ends up making you feel hungover, wasted, & dehydrated.  Maybe it’s from something else somehow, but it seems that was the thing that was “different” about yesterday.  Please note for all of you used to the live show, no beers were involved in the recording.
