I am cutting dairy out of my diet. So far I feel great without it but I hate the nausea. Other than saltines does anyone have any ideas about my nausea? I am also adding coconut water to hydration any ideas about coconut water? I heard it's good for you but I have stayed away from the ones distributed by coke and Pepsi companies. I assume they aren't as nutritious as they claim.
