Could Lithium Orotate be the best underrated supplement for quieting a noisy brain?

I am not looking for a stimulant buzz or raw energy. My issue is racing thoughts and irritability that ruin my focus. I have read that micro-dosing lithium is great for resilience, but I want to know your experiences. Is this the best over-the-counter mineral for stabilizing mood and clearing mental clutter so you can actually sit down and work?
