Vodka+OJ is a good combo. Even with cheap vodka+oj, the juice will mask the taste of alcohol very well.
Vodka+cranberry juice goes well too. If you're feeling fancy, you can also do 1 shot vodka, half shot triple sec, cranberry juice + a dash of lime juice.
But the best way to get drunk is do shots of vodka. Get some decent ones too, not the ones that come in plastic bottles.
If you're really concerned about sugar, just drink liquor straight. You'll have to develop a taste for it, though.
