I helped a friend on this "not liking water" issue. Something, something they can't drink diet soda no more, doctors orders, only water/juices. So i got her hooked on carbonated water. It sounds dumb, but just drinking it enough, it feels like you're just drinking bland soda. I mean wtf, it worked for her, i knew it would work cuz i had another friend who did this herself and just always got seltzer water... this girl used to be a Coke purist. How so? she'd order it w/o ice, she couldn't stand her Coke being diluted, then of course doctor said, you're dying! too much sugar, so she did the seltzer water.
I got her this

the soda stream, you've probably seen it, puts Co2 into water, then pour on syrup and you get ghetto coke or ghetto dr pepper.
It is super easy to use (i have one too) you just pop in the bottle, slap the button down, take it off then pour in syrup, only for you, don't pour in syrup, just drink it with co2. I'm saying this only b/c it because VERY expensive for my friend buying lots of seltzer bottles (cuz selzter doesn't go on sale really, i mean who drinks it for fun).
Just use filtered water(or you like the taste of municipal/well water) and you're good to go.
Also, each can is like 60L worth of water, each refill is 30bucks, however you can bring you're used up co2 canister to walmart,BBB,staples (and probably other stores just check the website) and trade it in for 15bucks filled. (there are other hacks where ppl get a scuba tank and shit, but whatever)
the bottles for this machine also have like a silicone thing in the cap, so your sodas keep their fizz in, once you recap of course. It's worked for 2 ppl i know, try it out.
