If sleep is cleansed, will there still be a window where one takes double damage?

According to the wiki, Sleep is not a debuff, but a form of CC with weird rules. The wiki states that, while drowsy can not be removed, Sleep specifically can be removed, not just the stun portion of sleep. However, even after eating oranges while sleeping, it still feels like I'm taking unrealistically high damage. Zoe is kind of overtuned in damage right now though, so that might be why.
