Becoming a Fairy- WAY too simple! (AND EVERYTHING ELSE, TOO!)

Genuine question: do we know what happens if you repeatedly only eat the 200 simoleon motive filler? Bc for the full needs spellcaster potion after i think 2 times it gives your sim the uncomfortable fast food moodlet, so you have to break from it if you want to get rid of that moodlet. I can't help but wonder if there is a limitation on it that simply isn't explored yet. I'm asking mostly bc i don't feel like watching a full youtube playthru to see if this was tested.
