Your lucky you live in SoCal, otherwise you really wouldn't have a chance. Anyway, I'm pretty sure loss of hunger/appetite is amongst the 80 or so LISTED ailments that allow you to get a card, but remember there is always "other" :rasta:. It depends on your doctors views on medical m, if he/she is against it or just ignorant, then it's going to be hard to get their signature, but if they are somewhat for it than they won't have any problems with signing it.
