I felt happier, calmer
The first day I used the Q-Link I felt a difference.  I felt happier, calmer, more centered.  The second day I didn't feel a thing.  I continued to wear it thinking maybe I had to wear it for a while for the benefits to kick in.  Unfortunately they never did.  Maybe that first day I merely felt better because I knew I had something on that was supposed to help me.  I don't know.
