The caffeine in coffee has a very strong smell and can cause the urine to smell-but if you drink enough water, the smell gets diluted. Another possibility is that you have a mild UTI-mild enough to cause the smell and the change in color of the urine but not strong enough to cause burning or urgency. Possibly the mld UTI and the decreased intake of fluids is related. I believe that you need to increase your daily water intake to at least 2 quarts.
