I think "sikuzote unakula" should also work.
What about Unakula saa zote? Isn't that more appropriate? You are eating all the time vs You are eating every day.
It is more appropriate. "Unakula siku zote" doesn't put emphasis on "always eating" since people eat every day.
"Unakula saa zote" or "Unakula kila wakati" would be more appropriate.
Would "Wewe hula sikuzote" work? I feel like habitual tense would fit for something that's "always"being done.
Daima should also be accepted
