Favorite summer drink is, without a doubt, a Mojito....also you mentioned drinks with a lot of carbs above. We're doing the whole low-carb/keto thing right now, so excessive carbs and sugar is a no-go.
My mojito consists of Light Rum, Club Soda, fresh mint, fresh squeezed lime and truvia instead of sugar. It's virtually indistinguishable from a regular Mojito (with sugar) and it's sugar free and no carb.
