where do you think you're going? to work, with you. it's taco tuesday. you're not coming. i took mucinex to help get rid of my mucusy congestion. oh, right then i'll swing by in like 4 hours. forget the tacos! one pill lasts 12 hours. i'm good all day. wait! your loss. i was going to wear a sombrero. only mucinex has a bi-layer tablet that starts fast, and keeps working. not 4, not 6, but 12 full hours. start the relief. ditch the misery. let's end this.
