Well there is L-theanine[0] which I always found was the opposite of caffeine, and when you combine it with caffeine (500mg theanine & 200mg caffeine), you get a sort of flow state without the jitters of caffeine. L-theanine takes the edge off caffeine. You could also just try L-theanine on its own. This person needs to experiment with other nootropics besides caffeine. I've tried various stacks over the years like Alpha Brain, Mindlab Pro and a few others. They've been instrumental in getting shit done on a tight schedule, and I don't get that jittery 'wired' feeling you get taking plain caffeine supps on their own, just a mild flowy state (thanks to the L-theanine).
