Do drug stores sell water pills?
Yes, most drug stores should sell water pills (either drug or herbal based ones) that will help to balance out the fluid in your system (not quench your thirst as some bad jokes go). They don’t have to cost a lot, but some ingredients are more expensive than others. Unfortunately, without knowing your area or what stores are available, I couldn’t say any brands, but there are a number of them out there. If you can’t find any in the store, I would just ask one of the people that work there where they would be. Good luck!
