Olly was fine. A little dizzy, but overall fine. At least, until his nausea became overwhelming. It happened very quickly and he did not have time to react. One minute he was sitting with his head on the desk, and the next he pushed himself back because he knew he had to vomit. He tried to find somewhere, or even run out of the room to a bathroom, but there wasn't time. So he threw up on the ground right in front of him. Gross. Luckily everyone else was also feeling the effects of the potion so they were probably too out of it to care.

Olly raised his hand weakly. "Professor, there's a situation over here," he managed to say feebly. That was enough exertion for the day. Olly laid his head back on his desk. Could he just take a nap?
