When do the effects of the pill wear off?

In the morning

The night felt like a dream to her, only until she woke up dis Uraraka realize it wasn't one. "Oh shit, it really happened. I fucked Hagakure." The effects of the blue pill had completely worn off, and luckily Hagakure was still asleep butt naked.

Uraraka then slowly piled up her clothes in her now skinny arms and tip toed to her room. She sat on her chair, gathering what exactly happened last night. She knew it had something to do with that pill. "I gotta get to the bottom of this--- oh shit! i gotta get ready for class" she realized when her alarm went off.

When she got downstairs fully clothed and heading to the kitchen to get her breakfast, she overheard something at the lounge area. All Uraraka can see was the backs of Ida, Kirishima, and Sato talking to most of class 1-A about something that happened last night.

"Oh no, they saw me" she said in her mind.
