What happens to the food Gil eats when he changes to and from a fish?
This is a bizarre question, and yet it’s been asked of me a few times . . . Basically, the contents of Gil’s stomach do not change, even though his body does. Therefore, if he’s eaten just before he becomes human he will likely find himself hungry again. Should Gil have filled his stomach prior to changing into a fish, the results would be uncomfortable (and possibly fatal) — if the pain of transforming was not so intense. If Gil should happen to change into a human on a full stomach, he vomits before making the full transition. As for alcohol and drugs, he has a very efficient metabolism. I assume the change sort of burns them both out of his system very quickly, but in doing so makes him feel really, REALLY sick . . . which may be why we don’t usually see him drinking.
