Please help! Our female veiled chameleon is egg bound and is calcium deficient, what can we do to help her??!?

We have a female veiled chameleon, and we recently noticed that she was hanging out on the bottom of her tank a lot more often than normal. After researching this behavior online, and taking her to the vet we discovered that she is egg bound, and is also deficient in calcium. We unfortunately cannot afford the surgery to remove the eggs by c-section. On the veterinarians recommendation we have been soaking her in warm water intermittently, and have been keeping her well hydrated, as well as feeding her *******'s repta aid once a day. We have also been giving her calcium in small doses twice a day. We have provided her with a 8" by 10" pan of sterile sand to dig in, but she has not been digging around at all anywhere in her tank. She has been much weakened, by all this stress though she has gained a lot of her strength back in the last two days and is a lot more active. We are extremely worried about her and will be extremely upset if we lose her. If anyone has any information on what else we can do for her, we would be extremely greatful.
