5/4, I went to reserve forces to train one day. After that I met people who studied about system simulation course with me and professor. I ate dinner and drunk alcohol a lot. And meeting is finished at 4 AM. Therefore I was so tired and had a hangover.
So I drank green tea for relieving hangover. A professor said to me if you drunk a lot, then green tea is very helpful to cure the headache.
Actually, at that time, I wanted to throw up, but I can’t. So I drank green tea. Maybe 5 or 10 minutes later, I felt that I should go to toilet to vomit. After that, I felt comfortable because it relieved headache.
Therefore if you have a headache because of alcohol, take a cup of green tea.^^
