Cognitive overload huh?
For me its how life is with or without electronic media, though of course the ability to consume over 50 hours of media per DAY does make life with all the media outlets extra taxing.
I have a.. condition? called low latent inhibition, which is both an advantage and a disadvantage, for example: I can usually watch two tv series simultaneously just fine, or text and drive. Okay thats not that good of a joke, I really really can't drive, at all.

How do I manage the constant load of information thats causing cognitive overload and burning me out?
well...
ADHD medication, good supplements such as fish oil, meditation, and proper diet.
