Coffee definitely! esp the first few minutes after consuming it when the altered state (caffeine high) kicks in. My belief is that your mind needs a state change to create a moment of insight/s. Like Einstein said, “We can not solve our problems with the same level of thinking that created them”. Not sure if I would classify a “eureka moment” as creativity. Eureka moments are bursts of solving/finding answers to something. I agree that they happen during relaxed states (non beta waves). Creativity is something that feels like it is more associated to a state of flow achieved when one is in the moment. The best “eureka moments” I've had were always in an isolation tank when floating like a cork all relaxed in 1/3 epsom salt. Such a powerful yet under used tool!
