Quieting Anxiety

I am being treated for anxiety with meds. I am in the process of stopping those and am enrolled for Perfect Health in Sept and attended A Weekend Within in May. My anxiety manifests in different ways depending on circumstances. My question is can I use my mantra to help me keep the anxiety from rising or will that reduce the effectiveness on my mantra? I usually just need to quiet my mind and hope repetition of my mantra is a good tool.
