if i brush them right when i wake up and before i get in the shower, by the time i go downstairs to eat breakfast, my mouth still tastes like toothpaste and my breakfast tastes terrible. if i brush them after breakfast and before i leave the house then my morning coffee that i drink on the way to work tastes terrible. if i wait until after my coffee to brush them right when i get to work, that's gross because i went through all morning without brushed teeth. so, i brush them right when i wake up, but i'm not the happiest with that arrangement. life is hard.
