I've been suffering of anxiety for decades. Nothing really serious. I stopped caffeine for one month in 2022, cold turkey. No coffee. No tea. No chocolate. I stopped alcohol as well (I don't drink much, so it wasn't really hard). I track a lot of things daily and during this abstinence period, my anxiety didn't decrease. On the contrary, it (very slightly) increased. This, of course, was not a controlled/blinded experiment, the duration was rather short (1 month), N=1, and I actually did two experiments at the same time (caffeine + alcohol), which is not optimal.

In summary, my conclusion is that I prefer drinking coffee (max 2-3 small cups daily, in the morning) than not.

Still, I'd like to try the experiment again in the future and stop caffeine for a longer period this time (3 months?).

Edit: I'm a slow metabolizer (rs762551 = AC).
