My favourite summer thing right now is flavoured water (still or sparkling). I keep a jug of water at home stuffed with sprigs of mint. Flavours the water without needing sugar. Other stuff I've put into the water: - mint and cucumber - mint and green apple - lime slices and cucumber - blueberries and cherries (sliced to extract flavour) - Strawberry and mint - Orange and strawberries Combos are endless. You just need to find the ones you like. Need more flavour? Add a tea bag and you have iced tea. If you do want something sweet, add some sugar, but the aim is to add less and less as you go. Your tastebuds will be trained to expect less sugar. So when you go back to coke, it will taste too sugary sweet to you.
