As I read this I am recovering from Tonsillectomy. I have been taking Hydrocodone/acetaminophen(vicoden syrup) every 4 hours for 2 1/2 days. I am very forgetful and cloudy. I work in pharma and this is definitely a side effect of narcotic pain medicine.

I would get to your neurologist as planned and sooner if you are very concerned, but narcotic pain meds will make you very forgetful and listless.
