and Brand's essence of chicken

I think a lot of people dislike the taste of Brand's essence of chicken but I really love it. When I was still schooling, exam time were the only time that I get to drink Brand's cos it's a bit pricey. Nowadays, I drink it whenever I'm tired and feel the need to get some extra energy and to wake up my brain. Today is one of those days. Hopefully, it will help me memorise Korean vocabulary and grammar. Help me please...
