You can replace the Red Bull with another black coffee and a glass of orange juice, the effective contents are the same.

I also absolutely do recommend to drink an acidic juice in the morning before any coffee, it brightens up the day significantly.

Could you elaborate on that?

[zaarn]

I find that acidic juices such as Orange or Ananas juice cleans out most of the gunk that builds up overnight and gives you a short boost through the sugar in them. The sugar can usually cover until the coffee after begins to work so you don't get that period of slouch after drinking coffee before it works (drinking something warm tends to make drowsy too so you possibly get more tired after drinking coffee). Skipping/preventing this short moment of weakness improves on the day a lot.

would adding sugar to the coffee have the same effect?

[zaarn]

Not to my knowledge, the acidity of the juice helps a lot to get more awake very quickly, pure sugar itself doesn't help that much to get the continous effect.

..but coffee is also acidic? what am I missing here?

[zaarn]

Coffee is mostly bitter in taste, Orange juice or Ananas juice is fairly sweet and acidic in taste in comparison.
