i had no idea so many people had the reversed curve! i guess its unlikely that the neck is the problem then
I felt I was walking with better posture, and had far less pain and discomfort in my neck. I also noticed a difference in my pectoral muscles. Most of all however, it felt (in sort of an intuitive way), that a marginal amount of curvature had returned to my neck, and as a result, felt much less stress in my neck than normal. It was like the relatively miniscule change in my neck curvature gave it more support. -- I'm continuing to experiment with this, and think there's a possibility I can refine what I did, replicate it, and possibly be a "good enough" solution for myself.
