Combine sugar and liquid ingredients (minus the lemon-lime soda) in a large, resealable container then stir until well combined. Cover then place in freezer overnight.
When ready to serve, scrape contents from container into a pitcher or drink dispenser filled with ice.
Add lemon-lime soda to taste then add wheels of lemons and limes to the container for garnish, if desired.
Notes
Just like the title indicates, this is one cocktail that packs a punch!
