Wow, I got pretty light headed but I did feel more relaxed.
I have always kept my shoulders up around my ears and in the last year as I have concentrated on lowering them, which has been extremely hard, my neck started to get sore, guess it wasn't used to having to do any work to hold up my head.
As a motivation to try to relax more, over the years of trying to make myself smaller I have developed a degenerative back problem from slouching and hanging my head, spondalolylisthesis, my spine has slipped forward on my pelvis. Another reminder of the abuse. I think it's a great idea to try and tackle these problems, they can physically damage you if you don't try to fix them.
