1. Excitement, because you can't wait to tell everyone what you're doing.
2. Happiness, because you are in a relationship with juice now.
3. Annoyance, when someone starts quoting a study that suggests juice cleanses are useless.
4. Obsession, because you are feeling so healthy.
5. Exasperation, when people ask you what you have planned for breakfast, lunch, or dinner.
