I have this weird thing where I find it very hard to drink still water, as in it scares me to do so (yeah I know it doesn't make a lot of sense but bear with me) so I drink anything but. So to down food everyday I drink coke, fizzy water, beer and especially juices. Now, my dentist complains to no end that this is bad for my teeth and she's even threatened not to treat me unless I fix the root cause. Which I understand 100%. However in the meantime I have to drink something, so...
I barely drink coke as it's extremely sugary and acidic which is terrible for the enamel (and can't be good for my overall health either). So I switched to fizzy water (fizzy drinks go down easily, water or otherwise, for some reason) but that's bad for your teeth as well. Fruit "juice" isn't good either. (note quotes, stuff from the shop isn't really juice, it's probably more like sugary water). Tea is hot and anyway it's meant to be had afterwards, so it's out as well.
So, my question is, is there any drink at all besides still water that can be had everyday which won't destroy my teeth and/or get me killed earlier than necessary? Preferably something that can be bought, though I'm not sooo lazy that I won't prepare it myself if I have to.
EDIT: the main reason I'm asking this is that I can't really drink plain water. as in, it kind of comes back up when I try to drink it (but only if it's plain water and only when I am not 1000% thirsty) (yeah it's weird). it's not quite that I'm addicted to sugar and I want to knock it off.
