Getting former F/T eater back from eating live

[Bogertophis]

....He looks almost embarrassed for me when I use tongs to "zombie walk" a dead one around. I've thrown away so many dead rodents in the last couple months, and am about ready to give in and resign myself to a snake addicted to the kill. But I thought I'd try you all just in case there's some hope, given that this same animal used to take thawed every time they were offered. Is there any way to flip the switch back?

I couldn't help it, you made me laugh. Been there, done that...wish I had an easy answer for you. "Patience" feels pretty lame to say, as I'm pretty sure
that some BPs love to frustrate us, it's their mission in life?
