Urine turns into thick dark color since yesterday?

Ladies & Gentleman, i need your help. Since yesterday afternoon, i had a 330 ML of 7 - 11 coca cola slurpee while going out with my friends. When i reach home, i go to the toilet & pass my urine. I was so shock that my urine turns thick dark color just as the color of coca cola slurpee. This morning my urine turns normal after drinking some water. This afternoon, i had a cup of coffee & the symptom still persist (urine color same as the coffee that i consume this afternoon). Is it something wrong with my kidney or bladder. I have no vomiting, lose of appetite & fatigue. Kindly please advise my what to do next.
