No, it doesn't seem obscure. Maybe the craving is "for the protein." Just like salt-cravings, being thirsty, etc. - I've heard that protein foods are something the body also can crave at times. Do you see all the literature on CAH & bones regarding the need for calcium & vitamin D? Really something to watch for as osteoporisis, etc. seem to effect CAH people often enough. Never know, maybe craving milk could be a craving for calcium or vitamin D even.
