There's a third way, very popular among hackers, yerba mate. Used by South American people.

It has good caffeine content, but apparently has a slower absorption. Helps you to keep focused, without the strong highs and lows you have with pure coffee.

Yerba mate is my favorite. I wish it was more popular in the US.

I stopped drinking coffee, the acidity was ruining my GI.

Switched to Mate or PG Tips tea as my morning drink, typically with loose leaf mate in a French press.

South American (Cruz de Malta , Taragui) are readily available on Amazon prime and much cheaper than the American brand Guayaki
