Sounds like our male spider. He would eat until he split open if you let him. We all have to play bartender sometimes and cut them off.
To the OP, you'll learn to read your snakes. Every snake will be different and what we've told you are just general guidelines. Sometimes you will get a bottomless pit who will eat everything in sight and never seems to gain any weight, likewise you may be lucky and have one that only eats a small meal on occasion, yet bulks up faster than Kirsty Alley and Rosie O'Donnell at an all you can eat buffet.
