Glad you had a helpful visit to David and no need to medicate at present. Hopefully Cranky will quit clicking soon. If you watch Snakebytes, they have an episode about snake illness and they use an inhaler/fogged of F10 to treat confirmed RI. Rather like longqi's suggestion of treating it like the flu.
Maybe there should be a sticky thread of home remedy's for suspected RI until they can be seen by a vet, it seems there is a few ideas floating around... although it may end in a mass flame lol
