(CNN) – Finally, the day we've all been waiting for: National Coffee Day (known for plebs as September 29).
It's a day for caffeine addicts, workaholics and Pumpkin Spice Latte enthusiasts to hit the streets to celebrate the only thing that gets them up in the morning.
So what's the real deal with coffee? Here are answers to some of your questions:

What is the difference between ice coffee and cold brewing?

Before taking the sigh of relief, you may want to summarize your coffee consumption today.
Conflict? Just wait.

Can coffee really sober you up?
We've all heard this at some point. Do you get tired after a few alcoholic drinks, but want power through the night? Get some caffeine in your system and you can go for a few more hours. Right?
Is drinking coffee bad for the environment?
 While the bean itself is natural, the coffee culture produces an absurd amount of waste. Let's see: You have disposable cups, filters, straws, plastic tops, mixers, tiny creamer cups, disposable machine cups, napkins, reason …. do I need to continue?
