Late night drink question

[Poledriver]

OK... Why is it that warm/hot milk drunk just before bedtime helps you get to sleep but cold milk just makes you need to pee?

Warm milk helps you to relax ( because its warm and soothing), which is a good aid towards falling asleep.

Sometimes a cold drink feels cold as it goes through your body. Cold can stimulate the bladder causing you to sudden feel the urge to pee.
