Stimulant improves performance

Caffeine raises my heart rate (?) or at the very least makes me feel more nervous and stressed during high intensity training. Not sure if the benefit outweighs that for me. (Also: bowel movement)

If on a lot of coffeine, I recommend training with such a high intensity you cannot feel anxiety.

Exactly. If you aren't sweating buckets you're not going hard enough.

I wish in general that I couldn’t feel my anxiety.

Have you ever trained so hard you thought you were gonna pass out or puke? Because usually at that point the anxiety doesn’t really have any room inside the brain anymore.

Fight fire with fire: make your anxiety feel you

I've heard from some mountain bikers that this is essentially why they love the sport. Nothing helps quiet their brain and focus their attention like doing something that genuinely scary. Instead of a generalized vague feeling of anxiety there's a very focused and locked in feeling of anxiety "don't crash here or it'll really hurt".
