Why are my lips and tongue numb after i drank 1.5 liters of white wine

I feel very much knocked out i can barely write its a very good feeling im numbed away too so i approve the ,,you can get drunk from 1.5 liters wine just like you get drunk from strong alcohol,, but im a bit worried because this completely numb lips and tongue and whole body no skin sensation thing has never happened with whiskey or tequila im a little bit worried
