I get sleepy whenever I work on my manuscript... I wonder if there's some good solution to this.Put on these wireless earphones. I'll remotely and periodically play the sound of a mosquito buzzing.With this high voltage electric machine that I made, any time you start to feel sleepy, you'll get shocked and forced to wake up.I'll release this cockroach in your room. See, with a cockroach nearby, you'll be tense and won't get sleepy, right?
