“Friends and family would say…what are you on right now?  I would just say I’m on sleep, I’m awake, I’ve got all this energy. And it’s an amazing thing. And it’s every day.”


“Before my procedure, I had a lot of headaches on a regular basis – I was missing work, not able to participate in my kids lives or family social life and those have gone away. It’s been very life-changing as I got my life back and I am able to fully engage and enjoy the things we like to do as a family.”
