Just because she can eat that much does not mean she should.
Snakes will severely over-eat. They can constantly look hungry when they are not as well. It is your job as a keeper to feed proper amounts of food per week. 4 mice being very difficult on the system of the animal. (plus, the snake should have been left alone for 48 hours after eating in the first place).
Get some proper sized rats and feed one every 7 days. Go either by the % rule or visual rule (prey should be the same thickness as the thickest point on the snakes body).
