Ex Input:
Was looking forward to this drink but was put off by its sweet soda-like taste.  Maybe it's an acquired taste? I'm not sure  but the high calories don't make me want to try.  Looking forward to a diet version.

Ex Output:

Ex Input:
Water tastes good. I typically prefer only purified water (did a study on this in grad school back in the day) but for use at the office, this fills the bill. I think it tastes good and looks presentable.  Bottles are (of course) recyclable, so I don't feel guilty saying I like the quality of the bottle as well. I once had someone pickup water, and they got a chain grocer brand at a steal - but the bottle was so flimsy. I don't like that one bit. This is the best of both worlds.  Shipment arrived fully intact for me.
