I’ve been using Paragon for quite a while and I definitely think its improved since V2. So far its been slow going but I stuck at it semi regularly, usually as the first instalment in my nightly stack, sometimes repeating multiple times in a night. Physical sensations I havent had for many years have been coming back in the last few days, suggesting at least its healing my sense of smell and touch.
Not sure how useful it would be in your situation since you’re using the physical shifting technology from Hero / ASPS which was derived from the same insights that built Paragon, and already have modules targetted to many of the areas that would otherwise be worked on by Paragon. Maybe ask Saint/Fire.
