As I understand it, Dr. Day only recovered upon following the Water Cure of Dr. Batmanghelidj, drinking 16 glasses of water a day. I've looked at Dr. Day's site and I don't see that she emphasizes Water Cure . Justin, if your aunt didn't drink half her weight in ounces of water, with the addition of Sea Salt as advised in Water Cure , that would explain the treatment failure IMO.
