What is your best advice for staying properly hydrated without spending a lot of money? Do you refill your water bottles or use a home filtration system or do you just buy bottled water on sale and whatnot? Can you recommend a good water filtration system or filter pitcher? If you have any tips, please let me know. I don't really like the tap water we have here, but I want to drink more H20. I also don't want to spend a fortune doing it. I refill gallon jugs sometimes, since it's cheaper, but I would like some other options as well, please. Do you drink any flavored water?
