There are plenty of alcoholic beverages that taste good. For the unacclimated taste theres Mike's Hard. Tastes like lemonade, there's a HINT of alcoholic taste but it doesn't ruin the drink. Same with Smirnoff Ice. Then for slightly more acclimated tastes there's (some) well drinks, lime-a-ritas, straw-ber-ritas, and various other flavored drinks (4loko tastes like stuff but it's not from the alcohol). Then there's kind of a taste curve for beer. You gotta find a beer which you don't hate drinking. For me this was Dos Equis. In the beginning I gagged after every sip, but now it's almost as easy to drink as soda. Once that one beer becomes palatable, others become easier. For me this was other light beers like Bud Light (Platinum), Blue Moon, Stella Artois, etc.
Hard liquor is a different story and that you only start enjoying after you force yourself to.
