Two things will impact this hugely.
One, hydrate. Drink water or other not-coffee, not-alcoholic beverages enough that your pee is nearly colorless. Lips dry out first when you're not sufficiently hydrated.
Two, petroleum jelly (Vaseline or any other brand) applied sparingly, especially overnight. No need to glob it on, just have a little on and reapply after you eat or when you're aware it's gone.
This is a fix that works, sometimes in a single day.
