Re:
Just for support, I'm in the same boat that you're in.
I've got 2 hatchlings I hatched August 4th that haven't eaten anything thus far, and I've tried every suggestion thrown out there. I also have a hypo lav from Rich's sale that has also refused feedings, which just aggravates me. Then, as I am reviewing my feeding charts, I have one of my own hatchlings that ate once on Aug 13th and that was the last time it ate.
So all 4 are now being cooled off for a few weeks and see if that helps matters any. I think it was Elrojo who stated that he's had variable luck with cooling them off and then getting them to eat. At this point I'm willing to try anything no matter how outlandish it sounds.
At the very least, it should make them last a little longer on no food, as their metabolism should be next to nothing.
As for butters from Rich, mine prefers his pinks/fuzzies scented with anole's. The T-Rex Lizard Maker stuff didn't work worth a hoot, it was the real deal he wanted. Even though he's eating good, every now and then he still wants me to terrorize my anole by rubbing a fuzzy mouse all over the anole cage.

So whenever you get better (I wish my infection would go away as well), I'd try and look into buying an anole for scenting and see if that encourages them to eat for you.
I just don't understand the whole non-feeding thing myself. Just doesn't make any darn sense.
