Summary
A Reddit user with long COVID tried low-dose naltrexone, starting very low and easing upward. Within a couple of weeks, at the second dose level, they felt generally unwell, slept badly, could not think, and had aches and headaches. They stopped it, and two days later came out of the fog, which they called one of the best feelings of their life, deciding with their provider not to restart.
