Brumation.. Should probably have switched off the heat, instead of turning it up.

The question is, which of the remaining tricks is the best. I'm not convinced force feeding will reset it, I did manage to sneak down a small scented mouse and that didn't do it.
So it's either sugar or brumation, and it has already been 5 weeks off feed, but at normal temps. So, how fast can you get it from normal to brumation under these conditions?
I'm really getting curious about how far it's willing to take the hunger strike.
