will drinking coffee in the morning make you need to urinate more at night when you are trying to sleep?

No: Caffeine takes 30-50 minutes to achieve peak blood level after consumption and its half live is 3-5 hours. Thus, drinking caffeinated beverages in the morning should not affect your urine secretion on the following night.
