First off, I want to wish you good luck with her!

Continue with the vet treatments to remove parasites, because that could cause her lack of appetite and her regurgitation, keep the high humidity like you have, but I'd suggest bumping up the temps to around 85 cool and 95 hot, it'll help her fight off anything she might have, and it'll also (hopefully) raise her metabolism a bit and she may be more willing to take food and may manage to keep it down.

Good luck, and keep us updated about her!
