I peel it because it is said that it can be as white as an apple. Just peel off the outer layer and keep the white layer inside. Then cut the lemon into pieces and throw it into cold water (for fear that hot water will destroy the vitamin C inside). It will taste sour after soaking for a while. It would be nice to add some honey. ...
Try to drink it at night. It is said that it is not good to bask in the sun after drinking lemons.
By the way, don't drink on an empty stomach, it will be uncomfortable.
