I almost never drink water. For some reason, I just don’t like it. I buy vitamin water which is ok. There are different flavors. Just make sure the one you pick has a hechsher – not all do.
Recently at a wedding, they served lemon water. I actually drank it. So I decided I’m going to buy lemons, slice them up and put them in the freezer, packed separately so they don’t stick together (my friend gave me the idea of slicing and freezing) and just pull out one when I want some water. I’ll let you know how it works. I plan on trying it on Pesach since vitamin water is not kosher l’pesach.
