First thing you know you will be extremely hungry. Not enough meat? Then you will be chewing on your own fingers, devouring your own skin. That's not all. You will get extremely paranoid and hungry enough for cannibalism. Then you laugh like crazy and then... you die.

You wake up, you're full of rage, hungry, you need to keep feeding, you must eat, you must devour... all of the living... fresh meat. If that living dies... it wont taste the same... you need to devour... find a new host.
