Thanks as always.

you know of a link/resources on how to achieve the safest posture while sleeping/working? I have avery hard time sleeping on my back. I purchased a pillow from these guys last year: http://www.omegaposture.com/
I don't think it is worth much if you don't use it right... and I just can't sleep still on it..
Also I have a quite soft mattress so maybe that also needs to change (?)

I am definitely going to pursue the neck issue at depth, and will update everyone.
