After drinking for about a month, I called my former classmates. As a result, they all said that my voice changed and it sounded better ~ hehe! The landlord must give it a try!
It's best to make oatmeal with milk for breakfast (raw oatmeal without sugar is sold in supermarkets, just add it to milk and put it in the microwave for more than 1 minute, which is delicious and can lose weight), whole wheat bread, and it's best to have another fruit. This is a western breakfast.
If you are used to eating Chinese food, any kind of miscellaneous grains porridge+vegetable buns+a boiled egg is also perfect ~
