Just read through your other post about weaning off prednisone - didnt reply because everyone said what I would have, only better!
I don't have a solution, but as long as the other meds are not something the doc has to administer themselves (through an infusion, like Remicade, or an injection, like methotrexate) I think getting enough pred to wean off safely (and slowly, veeeerrrry slowly) is a good plan even if it fdoes involve lying. i know most docs aren't sympathetic to this treatment, and that is a real bummer.
Have you considered contacting Dr McDougall and inquiring about doing a phone consult with him? I don't know if he does that, but he might, and he'd certainly understand the need to wean off slowly with a pred 'script, while also encouraging focusing on a dietary approach.
