I've been replacing most of my morning coffee with yerba mate. Yerba Mate isn't a roller coaster ride of highs and lows but a smooth, elevated sense of caffeine alertness.
I would have like that, but trialing it for several weeks it seems too much effort and caution is required (I.e. easier to ruin a brew).
I take <5 minutes to make a coffee from roasted beans, whilst yerba required expertly making a stable mound, priming an isolated kettle, then pumping water in slowly throughout the day as to not over-extract.
