Katie moved to stand, then faltered, her immense legs buckling underneath her. It wasn't from a lack of strength - no, she had plenty of that - but the pain that lanced up through her muscles. She groaned, loud and deep, enough that Tiff literally jumped, turning back just in time to see her friend crumple. "Katie! Oh my gosh, are you okay?"
"Oh, Tiff, I don't know if I can walk!" Katie replied, letting out another moan of pain as she forcefully stretched out her legs, doing her best to massage the muscles out. "They're just too sore."
Tiff sucked in breath with a hiss, sympathising with her friend's pain. "Don't worry, I'll see if there's something that could help."
She ducked to the bathroom, pulling out the drawer with all the first aid supplies. Inside were mountains of boxes filled with pills, though upon closer inspection, many had outlived their use-by date. Of course, no one had lived in the house for years, now, so there wasn't anything in-date, and, with the naivety that came with being sixteen, Tiff decided it wouldn't hurt Katie to take just a few. The only question was which one to take.
At first glance, they all looked to be rather reasonable pills. Ibuprofen, paracetamol, aspirin; standard fare. But when she looked closer, each of them had tiny writing, just like the milk carton, with strange side effects. 'Warning,' said the ibuprofen, 'Consumption may cause fluctuations in libido'. The paracetamol advertised that it would increase testosterone production. Aspirin brought on additional hair growth. And that was before factoring in that each one was out of date and would likely not work as intended anyway.
Still, Tiff grabbed the best option she could find and headed back to Katie, who was slumped in her chair, eyes closed and head tilted back. Tiff looked at her, then looked back down at the pills she had grabbed.
