First time drinking

I tried drinking for the first time and i started with 50 ml absolute vodka and mix it with diet coke but i didn’t feel anything and also it taste so bad and i thought it because i ate a meal before it so i tried drinking another one which is paulaner weissbier on completely embty stomach also didnt feel anything and also it taste gross

So what did i do something wrong do i need more or it just not for me
