Try switching to Matcha Tea. If you make it thin it has the same caffeine as coffee, if you make it thick it has 2x the caffeine as coffee. But unlike coffee the caffeine is basically time released, so instead of a caffeine rush followed by crash, you get a nice caffeine energy boost for 4-6 hours with no crash.
Its also the highest concentration of antioxidants know to man. Of course you only have a gram or 2 at a serving so its a deceiving stat.
