To log water consumption, start in My Daily Log, and select the Water tab.
Then, select a water glass to mark it as consumed. You can click as many glasses as needed.
To increase or decrease the default number of glasses shown, change your water goal under Settings > Health Goals.
Note: The volume of each glass represents 8 ozs / 237mL, but an actual volume does not log in your daily view. It's simply a visualization of your daily consumption which can be tracked over time under My Nutrition & Wellness > Hydration. It's not possible to change the volume represented by each glass in our platform at this time.
