This is my standard drink and it has caused more then one double post on more then one occasion. Quantity and quality count here. Way less calories then tonic water and much better tasting! Perfect Southern veranda drink! I have used other citrus with great results. I drink premium vodka and when only mid-grade vodka is available this will make it taste much better. So refreshing and a great pool-side summer cocktail! A splash of 7UP is a great topper. The amount of lime juice is up to you. Enjoy!
