At 600-700 grams, he has a little leeway, but not like an adult would. If he is starting to look visibly thin to you, it's time to cave in and let him have his mouse. Let him have 4 good meals, then hold out on him again for a few weeks. I try 3 on and 3 off. And by 3 off, I mean NO food at all for 3 weeks. Just water and cleaning. Then after 3 weeks offer a comparably sized rat. If he doesn't take the rat, wait another week and try a rat again. If he still refuses, let him have his mice for 3 feedings, then try again.
I successfully converted a few snakes this way. And a few still get their mice every week. I wish you all the best.

Thanks for getting back to me, I've never dealt with this before. I will definitely give this a try (and feed him his mice as soon as I get home).
