Notes:

1. Do not drink coffee or strong tea after drinking alcohol, because coffee can aggravate the dehydration condition after drinking, and Tea leaves the body in a state of excitement. Do not take a bath after drinking alcohol, because taking a hot bath can easily aggravate the user's drunken state and even cause vomiting and syncope.

2. If you take a cold bath, your blood vessels will constrict and may even cause blood vessel rupture. Also be careful not to take medicine after drinking alcohol, especially antibiotics, as allergic reactions such as rashes and laryngeal edema may occur easily.

3. Do not store wine with paint, gasoline, vinegar, and vegetables, because the smell of these items is easily absorbed by the wine and destroys the aroma of the wine.

4. Don’t go to bed immediately after drinking. Alcohol is digested by the liver. If you go to bed immediately after drinking, the body's metabolism will slow down, which is very harmful to the liver and makes it easy to get alcoholic liver disease.
