First, Cat, I have the same problem with my neckspine - backward curve. Fits right in with my bass-ackwards self, if you ask me
Second, yes, I have noticed that I'm calmer and more serene after an adjustment. It's easier to function for the first few days after an adjustment, partly I think, because my body isn't working as hard to stay in healthy alignment. Which means I'm in less physical pain. Which means I'm less anxious.
