Get a do while loop to getinput again? (C++)

C++

Hi, I'm trying to create a program based on some problems for beginner c++ online. I came across a problem trying to do this and I need some help

Whenever I go through the do while loop once it doesn't prompt me to input again?
Thanks

#include <iostream>
#include <string>

using namespace std;
int main() {
	string drinkChosen;
	string coke = "coke";
	string fanta = "fanta";
	string pepsi = "pepsi";
	string sprite = "sprite";
	string drpepper = "drpepper";
	string water = "water";
	int x;

	do {
	std::cout << "choose which beverage you would like" <<std::endl << "Coke, Fanta, Pepsi, Sprite or drpepper" << std::endl;
	

	getline(std::cin, drinkChosen);

		if (drinkChosen == coke) {

			std::cout << "you have chosen coke" << std::endl;

		}

		else if (drinkChosen == fanta) {

			std::cout << "you have chosen fanta" << std::endl;

		}

		else if (drinkChosen == pepsi) {

			std::cout << "you have chosen pepsi" << std::endl;

		}
		else if (drinkChosen == sprite) {

			std::cout << "you have chosen sprite" << std::endl;

		}
		else if (drinkChosen == drpepper) {

			std::cout << "you have chosen pepper" << std::endl;

		}
		else if (drinkChosen == water) {

			std::cout << "Please, you know you want a nice drink" << std::endl;

		}
		else {

			std::cout << "please choose again" << std::endl;
		}
		
		std::cout << "Please press 1 to confirm or zero to start again" << std::endl;
		std::cin >> x;
		
		
	} while (x == 0);

	
	
	

	system("pause");
	return 0;
}

What I have tried:

I have tried to move around the "string drinkChosen"
I have also messed around with the while loop's conditions
I have also searched this website and stack overflow
