I can’t say I have experienced that effect from a hangover, but I get what you’re saying. Like Scattybird, I am sometimes more efficient when I am tired. It also happens when I’m sick. The lack of energy makes it impossible for any non-essential systems to function, so everything is shut down except for “life support”, the basics that you need to get through the day.
Then there are days like today when my energy reserves are so depleted that I can barely manage to do anything except sit like bump on a log and watch life go by.REPORT ABUSE
