Can you describe what else you tried? Other supplements? Any other non-food/supplement techniques like journaling, breathing, etc.? Any therapy and other similar human interventions?
After all those - is it / was it still the case that cutting caffeine drove the best outcome?
Not OP but I'll share my experience. For me, I have to quit caffeine for those to even become an option. Otherwise I get my short burst of productivity then everything shuts down after and I don't want to do a thing, everything feels "impossible" or like it doesn't matter at all.
Things like journaling / breathing / etc calm the nervous system while caffeine stimulates it. I would say caffeine is counterproductive to those practices.
