I use BodyArmor in my water each morning. It has electrolytes, Antioxidants and B vitamins which give you energy. I also use Propel. So I add like a half bottle of each with some regular water and drink that throughout my day. But late afternoon I switch to regular water because the B Vitamins in Body Armor can keep me from sleeping good. Doing this concoction every day has helped me alot with my fatigue.
