How to drink more water!!!
If you think you’re not getting enough water each day, the following tips may help:
Carry a water bottle for easy access when you are at work or running errands.
Choose water instead of sugar-sweetened beverages. This tip can also help with weight management. Substituting water for one 20-ounce sugar-sweetened soda will save you about 240 calories.
Give your water a little pizzazz by adding a wedge of lime or lemon. This may improve the taste, and you just might drink more water than you usually do.
