Long Island iced tea isn't for the faint of heart (or liver). Serve this stiff drink in a martini glass to encourage slow sipping.
Combine first 7 ingredients in a cocktail shaker or martini shaker. Cover with lid, and shake 30 seconds or until thoroughly chilled. Remove lid, and strain into 2 chilled martini glasses. Pour 3 Tbsp. cola into each glass. Garnish, if desired. Serve immediately.
Sweet-and-sour mix is sold in bottles similar to Bloody Mary mix.
