I think it might be a good idea to leave some vegetable stuff in there somewhere for the crickets to munch on - i case they start nibbling on the ackies. I feel your pain though - I've got this problem coming up soon - the snakes are so easy to just go off and leave for a few days - but lizards do need more attention. They don't poop in their water do they? (My monitor does sometimes) it might be handy if someone could pop in and check poop/water.
