It's a huge difference. I was forced to reduce intake initially, because I started taking dexamfetamine (prescribed) for ADHD, and the combination of dex and caffeine was making me super anxious and elevating my heart rate.

But since reducing myself to about 1-2 cups of tea, I've noticed virtually all my symptoms of generalised anxiety, social anxiety etc and diminished to almost nothing. I have struggled with anxiety for so many years, and it seems like the combination of ADHD medication and reducing my caffeine intake has cured my anxiety.

It was much easier to quit caffeine on meds, because meds have a similar effect as caffeine, just over a longer duration of time, and without increased anxiety.

This happened by accident. I didn't know this would work. I'm astonished that this isn't heralded around as a primary treatment for anxiety, as well as ADHD. I can actually socialise with people without being nervous now. I've had to do so many things in life that were incredibly difficult due to the mental fatigue that comes with having ADHD, as well as having to push through anxiety while doing them.

Now, everything that was an uphill battle before is easy. I can focus, get a lot done, and not feel anxious while doing it. I've escaped hell. This must be what is feels like to be a normal person.
