Like I shared elsewhere, Charlie, you already did all you could to kill that inner ear, so doing so surgically I guess is not a big deal. You're just confirming what choice you already made... and it did seem to help for a period of time.
I was surprised to read you'll be inpatient for a period of days...but I guess that close to your 586 Chip, they want to be sure you don't get any "bugs" or earwigs in there so they'll keep you for a couple!
Does make the "reality" of it all a bit more serious, but Lord's been with you this far, He will not fail you now!
Prayers will abound on the 24th and thereafter till we hear from you!
Lord in your Mercy...
