| I'm currently experimenting with a low caffeine (no coffee, mostly green/herbal tea) lifestyle after having the stomach flu (no coffee for a week) and thinking it was the perfect time to give it a shot. My god, I've never been more clear-headed in my life. My working memory seems greatly improved. I'm able to work out complex problems in my head that previously I would struggle to keep my "mental eye" on. Moreover, I'm much less anxious in general and generally much happier. I think I'm ADHD/anxiety-prone and I think that, while coffee for some with ADHD really helps, the increased anxiety made it difficult for "long, slow" mental processing to occur in my head. A confounding factor is that I've also recently introduced a green powder in my diet, but the effect of no-coffee has been much more immediate. I love coffee and never thought I'd be able give it up, but I don't even miss it now... |
As I recall caffeine has an effect of "enhancing" dopamine sensitivity in the brain which is the likely cause of this effect. Could probably reset this over time, but don't really have multiple weeks to wait this out!
