Hello Mitchell,
I am not an expert but I have read similar descriptions and they were pointing to your “symptoms” as signs of good progress. Culadasa himself described during a recent retreat that I attended the reduced need for sleep as a normal stage along the path.
In any case, a good suggestion that I got from a teacher recently is to take everything with a hint of lightness and detachment. Some humor and a little indulgence, in his words, will go a long way.
