Headache...

Prognosis:
Brain Binge-Eating

Cause and Effect:
Listening to Japanese all day after a 4 day weekend of mostly English causes immense pressure to the head and gives the impression of continuous pounding, making the ears and frontal brain lobe feel as if they are going to explode. This brain binge-eating is the result of a flood of Japanese into the ears after a 4 day fast.

Solution:
Sleep immediately and dream in English.
