I think that either the Lupron or the Superlorin implant is the way to go. Another benefit of the hormone injection for budgies is that blue budgies are prone to reproductive tract cancers/tumors and those are treated with the same protocol, so by treating one problem, it puts Biscuit at a lower risk for another potential issue. How old is Biscuit, by the way? I hope that regular hormonal treatments get her well, and that you don't have any more emergencies with her.
