My husband is an avid energy drinker cause they help him get through his work day,he works 12 hour night shifts. An he just got his fillings fixed but can’t really drink energy drink for about 6 months or more cause he has teeth that might turn into cavities they said so he’s trying to change up what he eats/drinks. Anyone have any good recommendations for drinks we can buy or make that will give him a good boost of energy at work that taste good but doesn’t have all the sugar an such???
