Underrated best mix drink for vodka with healthy properties

I will be the first to say that my favorite alcohol is vodka. Hands down it goes down the smoothest but it is still strong. Some have a difficulty drinking it even when it's mixed with something like orange juice. Sometimes they have to put in such a small amount of vodka to drink it, it'll take ten drinks to get a buzz. The struggle to enjoy vodka is over with the simple addition of a different juice. This juice is none other then grapefruit juice. Now I know at first glance everyone is saying yuck and my love of the taste of grapefruit would cause you to feel some bias from me. However, I'm not asking you to now think this is going to be a grapefruit tasting drink. Hear me out before you say gross. the way the vodka mixes with grapefruit is different then other juices. The sourness of the grapefruit juice will cause the vodka taste to dissipate. What I mean is you will taste a slight sourness rather then strong vodka. Now the best part of this is you can mix any cheap vodka with it and feel the effects. I will ask you to try this, buy the cheapest vodka you can at the store and mix it with grapefruit juice. After you have done this I will ask that you leave me a comment stating that what I'm saying isn't true. Now I'm not saying you're going to love the initial taste of the grapefruit juice but tell me it doesn't make cheap vodka easy to drink in large amount. All vodka will taste good with this juice. You can also put a lot more vodka in that drink then you're probably use to when you mix a drink with juice and vodka. The name of this mix is a greyhound. But since this is kind of dated I'd ask for a vodka and grapefruit if you are out. Remember if you are a health freak that grapefruit juice is the healthiest of the juices mixed with vodka so drink up it will not hurt you. I'm not a doctor but I am a gym person.
