This file will make your brain feel extremely fuzzy and slow for the rest of the day. It will especially affect how you talk and write, reducing your vocabulary to the level of a four-year-old. You'll be unable to think of any long words at all and will not understand any words that have more than two syllables. If you try to write, the letters will look like a little kid’s writing. In addition, everything that requires any thought will be much more difficult than normal, so you won't be able to perform even the simplest tasks. Your brain will feel slow and unable to think for the rest of the day, and then you’ll be completely back to normal when you wake up tomorrow.
