how do I get the juice quirk

....Trying to get this in my game now, and having the same issue as @comicsforlife My sim is drinking orange juice, bar juice, any juice he can get his hands on. For 3 sim days, he hasn't eaten anything because all that juice is keeping his hunger bar full....still no quirk.

I even learned something I didn't know and that is that our sims can be two-fisted drinkers:
