I might add - just to be secure - that if you also bought the charger then you should plug the unit in for awhile and let the Reader get completely charged.
One time I was careless (I was involved in reading a great book), and the unit gave me a warning that my battery was low. I immediately turned it off and plugged it into the wall using the AC charger.
Curious: What "madness are you gorging yourself on?"
