When I gave Jack two fuzzies, he regurgitated one of them. I'm really nervous about trying two again any time in the near future. Sally and Ky-Lin though handled two just fine, so Jack may just have a more delicate digestive system. I gave him just one last time, and he did fine.
You really probably should try switching to frozen/thawed fuzzies as soon as possible. If you feed live too long, your snake may give you a super hard time about changing. You don't want to end up where you have to give him live adult mice. A live adult mouse can do serious damage to a snake and even kill them.
We buy ours frozen and thaw them in warm water (changing it several times to keep them warm). You have to be sure they're completely thawed, as you don't want the snake eating one that's still frozen at all. If the snake won't take it when the mouse isn't moving, you can use feeding tongs to jiggle it a bit.
It's really worth switching to frozen/thawed. It saves a lot of worry, and you don't have to listen to the mouse scream...
