Once in Korea I had been given similar drink by an old women. It really worked. That day I was drinking from evening till 3~4 in the morning. I was hardly able to walk. I went to a small shop for water and an old lady gave me this drink for free. I just slept for an hour and at 6.30 I was fresh enough to go to office. After coming back from office I went to the same shop asking about the drink and I guess the same lady was there. She could recognise me and asked how was my day. Thus I found the Magic drink.
