Has Anyone Tried Over The Counter Pharma GABA For Stress?

I am trying to better manage my stress because I think it contributes to my increase in migraine episodes.
A friend, Who also has migraines recently tried GABA and she thought it helped relax her. It’s a chewable form at 100 mg. I did some research and I did not read anything troubling about it.
Thank you for your responses.
