I would normally judge you, but I've definitely gone a similar route - our office had a Keurig machine (as a gift from some vendor) and a supply of crappy K-cups that no one else wanted. And all I needed was a caffeine boost before going to the gym. So all the things just aligned for me to use both the machine and the (frankly terrible) coffee it made. Can't beat free. Even if it is terrible quality. But in the future, I would probably just go with a 150mg caffeine pill, simply because it produces less plastic waste (I hope?)
