Well, you did feed her a pretty big meal, and it could be that she feels too insecure after being held immobile to digest - since in order for them to properly digest, they have to have belly heat to help.
For feeding, I would go with what everyone else has been suggesting - a fuzzy a week. Again, you'd be surprised at what they can handle!
Also, I know of the perfect place for you to get mice:
http://www.coasttocoastmice.ca/ont/
I've been ordering from them ever since I first got my snow corn (possible bubblegum, like yours!
) a year ago. Though I don't order from the Ontario farm (because I'm in BC), I wish I did! The mice in Ontario are sooooooo much cheaper than in BC.
Also, what you might want to follow (and what is recommended by some owners who find it successful) is the Munson plan. The plan basically dictates that the size of mouse you should feed depends on the size (in grams) of your snake. This is generally accepted by the Munson plan:
-When they're on single pinks (2-3g), feed every 4-5 days. (Snake = 4-15g)
-Double pinks (3g x 2) every 4-5 days. (Snake = 16-23g)
-Small fuzzies (5-7g) every 5-6 days. (Snake = 24-30g)
-Regular fuzzies (7-9g) every 5-6 days (Snake = 30-50g)
-Hoppers (9-12g) every 5-6 days (Snake = 51-90g)
-Weaned (14-20g) every 7 days (Snake = 91-170g)
-Adult (24-30g) every 7-x days (Snake = 170+)
-Jumbo Adults (40-50g) every 7-x days (Snake = 400g+)
Aaaaaand, the last two lines depend on gender (that's why there's '7-x), so if you have a female, they recommend (remember, only if the snake is an adult) that you feed every six to eight days, and males every seven to fourteen days.
And if you don't know how you're going to weigh your snake, you can just go to Walmart and grab a food scale that can weigh in grams - they usually sit around fifteen bucks. Oh, and don't worry so much about weighing the mice themselves, just remember to ask for the right size, you know... 'pinkies', or 'fuzzies'.
Hope I'm not bombarding you, it just looked like I was needed.
And remember, what others do might not work for you, but you should try it first and see for yourself, then decide.
