The real 'adun' no be say the leaf go turn sweet by itself. Na when you follow am with something wayyyy sweeter, like honey, or even better life outcomes, wey go cover the bitterness completely.
Actually, the proverb never says the hardship will vanish. E just dey remind us say after the ewuro stage, make you no dull, go and find/create the thing wey go sweet your mouth pass the bitterness.
Forget the cruise, proverb and its figurative meaning, there is absolutely no sweetness after eating ewuro. That thing is sooooooo bitter 🤮, even after extracting some of the bitter juice from it.
