Chilled Out Lemon

Using a frosted glass, half fill with cubes of ice.
Then add a double measure of Vodka.
Add 2-3 dashs of bitters and then a single squeeze of lime (too much will overpower bitters).
Stir the mixture slowly and then top-up with lemonade.
Taste mixture and add either an additional dash of bitters or a squeeze of lime to obtain a taste similar to cola bottles (the sweets).
