Juice doesn't get enough credit. Just regular OJ, or Grape juice, or apple juice, or pomegranate juice(my favorite), or cranberry juice, or whatever... Fruit juices are really nice.
PRO TIP: To motivate yourself to get up in the morning, whether it's to prevent sleeping through your alarm or you feel too crappy to get up, take your favorite juice and pour a cup of it and freeze it. In the morning take that sh*t out and bask in it's sparkling glory bc it's the best thing ever and you should be proud bc you made a thing. It's a makeshift popsicle, but you eat it with a spoon, out of a cup. It's delicious.
