Who doesn’t love a tropical cocktail poolside while on vacation? Bring some of that relaxation home with you and mix up your very own Painkiller. With a name like that, you are sure to think of several situations that deserve a little indulgence: The end of a long week at work. Nursing the sunburn “souvenir” you brought home from your getaway. That gruelling workout you just completed. Surviving yet another commute through rush-hour traffic.
