Do you know how much it affects your deep sleep duration?

People who drink caffeine at night may claim to be able to sleep still, but they will find that deep sleep stages are shorter, which is significant because it may be the most important type of sleep.

I never slept as bad in my life as when I had a single can of coca cola at 8-9 pm and went to bed at 11-12pm

I did this for a while working nights until I caught on. The nights I didn't have a can were much better.
