You probably haven't found the right alcohol that agrees with you. Wine, beer, spirits (whether alone or in a mixer) have myriad tastes and flavor profiles. Saying alcohol doesn't taste nice is a bit like saying "I could never be a vegetarian because all the foods taste the same."

Not judging you BTW. In the long run not drinking is probably healthier than drinking. Certainly the case if one struggles to control the quantity of drinking.
