It would be really nice if Mafia could take a shot at estimating the fullness used from the random result of a quantum taco. Although I wouldn't expect anything like consumption message matching (seems like it'd be way too impractical to implement something of that magnitude for something so inconsequential), there is a kludgey backwardsish way to sort-of measure that by monitoring and recording the number of turns of Got Milk lost upon consumption. Obviously, that would be far from perfect--it'd only work if the character had that in the first place and wouldn't account for the effect running out before all the fullness is accounted for--but it would at least be SOME manner of tracking it internally, even if only partially, that existing remaining fullness estimation would be able to work with.
