Cognitive test show that coffee drinkers merely recover from withdrawal, and the effect isn't an enhancement on those that don't drink. They do worse when they haven't had their coffee, and associate this with stimulating them, when actually they are merely functioning as they normally would, if they weren't coffee drinkers. This is a general trend and doesn't account for different nuerotypes.
Non-coffee drinker do worse after drinking it.
Having said that I sometimes drink it. I do very little without moderation. I'm not boasting, I just have some built in function that doesn't like too much dependency.
Coffee does have other benefit so it is not all one way.
Coffee can make be jittery, and anxious too. Ironically stimulant tend to make me feel drowsy too. Dextradine puts me flat out to sleep, is is pretty ironic given it is used to treat narcolepsy.
I drink tea very weak. I poor through the tea bag, and take it out. I drink camomile, which obviously not comparable.
I take sage pills, due to studies on it an attention/cognition.
I do like eating coffee beans sometimes, becuase I'm a fan of bitter. I eat bitter guard. I don't think bitter combines well with umami in equal measure in the same mouthful. Mushroom that have to much bitterness, are not. It depends how you cook them, and the variety.
