A friend of mine gave me Pure Inventions - Pure Hydration - Coconut Water Enhancer (30 Servings) 1 Oz and it was AMAZING! I have ordered the other flavors off of Amazon and am looking forward to trying them.
I use lemon juice, cucumbers, and ginger. I have used mint leaves. I also use lemon power with electrolytes especially since I'm doing Keto. I also do a lot of tea lemon zinger, green tea, and peppermint tea.
I've sometimes pureed a little bit of a sweet/sour fruit and added it to me water. Watering down some pineapple juice might work for you. Remember, you CAN drink other things that count as water because it is really fluid .... ALL fluid that is important.
In the summer I often have an iced tea and add a splash of sweetened soda to it which lifts the enjoyment. It is also generally the only time of year I would meet/go over the 8 cups a day, but not every day. In the winter I often only get 5 cups of fluid. That is because in the winter I tend to eat more soups/casseroles than the summer. I eat a heap of fruit every day and a lot of fluid comes from them, as well as other foods.
Be guided by thirst and the colour of your urine ... if it is pale yellow or clear you are generally getting enough. If it is darker you may need to drink more.
There are a few different things that you might experiment with:
1 - Temperature While lots of folks prefer icy cold water, there are lots of us who detest it and prefer room temperature or heated. You might find that something you loathe cold - say, lemon infused - tastes good to you at room temperature, and is quite enjoyable at "coffee" temperature.
2 - Tissanes (herbal "teas") Without using actual white / green / black tea leaves, there are tons of different tissanes that you might enjoy. If you prefer "sweeter" flavours, then look for mint or cinnamon or citrus blends --- or look for ginger or lemongrass if you like "sharper" flavours. Don't forget to try them at different temperatures, and at different strengths (for instance, I really enjoy a very light strength of lemon ginger at room temperature --- but can't swallow it if it is too strong, or if it is either hot or cold --- and I love hot water with a squeeze of lemon, but dislike it at room temperature or cold).
3- Teas or coffee While some folks claim that these "don't count", your body will use the water from them just the same as it does water from any other source. If you really enjoy these - at any temperature - then keep having them. The only caveat is that you might want to seek out decaf versions, since there is a healthy upper limit to caffeine intake in a day.
4- Broth Whether bone broth (meat based) or vegetable broth, the liquid content is absolutely used by your body as water --- and the extra nutrients are a bonus. If you enjoy the flavour, at whatever temperature, then sipping at a few cups of this during the day definitely "counts"
Finally - assess your thirst level and urine colour, and then decide whether you actually are already getting in enough fluids and don't need to worry about finding a way to "like" water! There is no scientific basis for the "8 cups per day", and many people don't need it since they get sufficient hydration from their food choices and other beverage choices.

"Science is not about building a body of known 'facts'. It is a method for asking awkward questions and subjecting them to a reality-check, thus avoiding the human tendency to believe whatever makes us feel good."
