Sophia Late Night Thought Protocol
Thought loops at night are your brain's attempt to process unfinished cognitive business. The loop persists because the thought hasn't been fully expressed. Writing it out completely — the whole thing — gives the loop a terminus. Private, offline, and available at any hour.
