It tastes like everything and nothing at the same time. Maybe its just our brand (filtered cirty water because I refuse to pay for bottled water), but I only drink it flavored unless I have to.I've noticed most people who hate water have texture or taste sensitivity. My middle child is like that, she drinks a lot of hot tea and needs the water to be super cold and full of lemon to drink it. She actually says water tastes sweet to her, she's tasting the minerals in the water. There's a also super tasters, those are usually people who can only eat a handful of things without gagging, it's a real condition. They have a special protocol for super tasters, I have not learned that just yet.
Unfortunately I can't use the flavor packets after brushing my teeth at night do onlynplain water is allowed in bed
