I also drank a little pickle juice! Not sure I am recommending it necessarily but it sure helped quench my thirst and gave me a little savory flavor. I also drank a LOT of Propel Fitness water and PowerAde Zero. Hang in there! The first couple of weeks are the toughest!
Are you only clear fluids or full fluids? Try Vitamin Water (No Calories), decaf tea, sugar free popsicles, infused waters (try different flavor combinations). Use spices in your broth to make it more appetizing. Good luck!
