I'm up in the morning, but feeling really sleepy. While doing my stuff online, I decide to get an energizer to wake up a bit. It's so bubbly that I start burping after every sip. Sometimes the burps come so unexpectedly that I'm surprised and can't stop giggling. Still, I can't wake up and continue yawning hard, my mouth can barely hold my yawns, I'm even starting to worry for my jaw
