Well, I'm not sure there's much advice I can give you, other than perhaps keep in mind what needs and limits you had before you were changed the first time. Some people arrive here who were never human in the first place, so if you can recall that much you'll probably be in a better position than they find themselves.

Other than that, if it's any consolation, there's usually two periods of a few days each year in which peoples' original powers and forms are temporarily restored.
