She sounds like she is stuff to the max. How was this guy feeding? what size were the mice in comparison to her girth? Did she 'kill' each mouse and eat it? if they were frozen/thawed mice, were they completely thawed? were they strung together w/ string? As much info as possible would be helpful.

Make sure your temperatures in the enclosure are correct....92-94 warm side/ 82-84 cool side. I would prefer the temps to be in the higher regions of those ranges, since the lady has just had such a big meal (it will help her digest faster). Also, snakes should not be handled for 48 hours after they eat so avoid handling.
