ranjit If you're good at visualization, keep trying to visualize you're in front of an audience when practicing.
I always felt that if I could regularly and repeatedly experience playing through the shakes, I would learn to not be bothered by it a lot more quickly. But I have never been able to recreate the true "shakes" during practicing or in any non-performance situation. Still, I agree, visualizing is really helpful. I also try to remember the shakes and what they feel like so I won't be surprised when they occur.
I've also thought of practicing performing with a "cough track" playing, or with pencil sounds on paper (this really gets on my nerves when my teacher writes while I'm playing and I can hear it constantly, like how the pencil starts to sound as soon as you mess up something tiny...)
I can totally related! I am pretty sure my hearing sensitivity jumps up when I'm practicing, and the littlest noise is amplified in my brain!
