Yes, my daughter just pointed at me, when I read this question. She purchases flavored water, both flat and sparkling for us. She also just found Propel makes a vitamin boost water in mango/peach, strawberry/raspberry, apple/pear, we haven't tried these yet. They also make paks you can purchase of the flavors to add to your water.
We recycle our bottles.
Kate's suggestion of lemon or lime juice works as well, as does cucumber/mint.
I hope this helps.

Yes! It helps when I squeeze some of fresh lemons or even limes
into my bottled water. The tap water where I live is nasty and extremely “hard”with calcium carbonate. I switched to bottled water a few years ago it made a big difference. I stopped buying individual bottles Jan 1,2020 to take an action to help the planet.

I add a little Gatorade to flavor my water and since my mouth is always dry I helps me to have ice in it.

I use packets of propell for electrolytes. Pretty good!
