I would happily re-mortgage my house to afford surgery which would leave me with a brain that works as you describe.
I too would love for a few breakthroughs to make it possible to do one-time correctional procedures for stuff like this.
I am adversely effected by all manor of sensory offence — including motion in my peripheral, heat, smells, unpredictable vibration.
The real problem is that it's a downward spiral: if something is bothering me and I become agitated, I am far more likely to become aware of other things which conspire to keep me from being productive. Ultimately, I fall into a state of manic anxiety and get really down on myself for feeling so ineffective.
I really wish I could just put in earplugs. They irritate my ears.
