Up to the "regen food" part I almost thought this was a serious idea...
Though I think JC once said he thought about food giving it's FnF also when eaten instead of gluttoned.^^
In case you actually are serious with that:
Having QnQ reduce by itself over time is obviously in contradiction to the current implementation where it is meant as an incentive to do gluttony/cravings and act as a penalty (no more drinking) if ignored for too long.
How do you cope with this point?
