Too Much Mice to Feed?

My little boy ball python ate today!

I have a 3.5ft female ball python who ate 3 hoppers for me on Thursday and Friday (I know that's quite small); however, I upgraded to Medium size mice. They look about the right size. She's looking around like she wants another one. Can I give it to her? Will she overeat?

I have a young female that is about 1200 grams that will eat 2-3 medium/large mice at a sitting with no problems.
We go by weight, not feet ;)
