Nerivio lets me get my migraine attacks under quick control (as long as I'm home and can use the unit). The other interesting thing is that I sleep better after using Nerivio for my migraines so I wonder if this technology can also help with insomnia? The one thing I wish was possible is to reuse the unit by having it "refilled" electronically and getting new pads to stick to my arm as opposed to having to keep purchasing all new devices. I especially don't need the box, arm band, and paperwork with every unit I purchase. Finally, I wish it was easier to get Nerivio with insurance. It's shocking to me that insurance will pay 100% of my Nurtec costs, but not Nerivio.
