- 2-3 lemon slices
- a little drizzle of agave syrup (maybe 1 teaspoon)
- TINY pinch of low-sodium salt substitute. Read the ingredients. You want something with sodium AND potassium. I use something that is half sea salt (sodium chloride) and half potassium chloride.
I use a water bottle that opens completely and is easy to wash. I love my Thermos Intak Hydration Water Bottle. You can get it at Target or online, but only in North America, as far as I know. I have my parents bring them. Costco also sells a three-pack on a nice bottle, but it's a little harder to clean, so not great for anything besides water.
