Water shouldn't have any flavor, if it does you should try filtering or buying a different brand.
I'm lucky enough to have well water that is wonderful, sometimes I crave it really cold, not sure why.
If you're drinking bottled water you might try different brands, I've noticed that some really taste like the plastic bottle, some have minerals, etc. that give them a different taste.
I used to drink alot of crystal light or store brand flavorings, you could try different ones of those to find a flavor you really like.
WW used to say you could drink half of your water as diet, non-caffeinated beverage, I'm not big on carbonation, so I like the unsweetened tea, etc.
best of luck
