It is helpful if you can start treatment immediately, either within 30 minutes of when the migraine began or prior to the pain becoming worse. My problem is occasionally I wake up with a migraine, by then it's past the 30 minute mark. The migraine has progressed past the initial stage, which is why I awoke. Although, the 1st time I used Nerivio, it was over an hour of onset because I was out at a show and did not have access to the device. I had to sit through the 2nd act the drive home before I could attach it. My biggest issue with device is it's not portable. I appreciate it fairly small, mostly lightweight, but it's not as convenient as, for example Ubrevly. Medication comes in small individual packets or you can put a stash in a small pill box which I do for my Ubrevly, Naratriptan & Excedrin. So depending on the pain, I have multiple options to choose from to address my pain - and to prevent a migraine from evolving into a bad situation. If possible, shrink it even more. Make it slimmer and lighter. Eliminate the armband. As a woman, we already carry way too much in our purses. I don't carry it with me everyday for pain management because it would take up too much real estate in my purse. I can't imagine what it's like men who generally don't carry bags!
