They both mean the same thing, it differs on the usage of the word. you can say:
I feel drowsy and I feel sleepy.
but you can't say:
This medicine causes sleepiness.
it should be:
This medicine causes drowsiness.

@x_zrii ok, either be medicine or not, can I use sleepy or drowsy? The same? In any occasion? But drowsiness only is used for both when it is a noun?

@x_zrii but I understood better what you explained. So I wanted to know if I could use both the same in any occasion . And “drowsiness” is only used as a noun for both, right?

@Er-tae yes, you can use both in any occasion and sleepiness is also used as a noun.
