The first time I tried it at home it negated the migraine! !!!!! I sat & listened to the breathing technique on the app. I used no additional meds all day. The second time I used the Nerivio device, the pain lowered but came back in a severe way & I chose medication to diminish the migraine because I had a few things to accomplish. Today I used it as I woke up & felt the migraine. To be honest I went to bed with head pain but didn't want to try anything else. I feel more relaxed but a migraine is still lingering. I will probably give myself another treatment with the Nerivio in an hour or 2. I fell the questions that are in the pro drome phase and the post are not sufficient for me. Wake up with a migraine should be there, confusion/ brain fog, Severe to moderate is a big jump for the pain levels and ability to function. I am GRATEFUL for this device as it offers me an additional way to help my migraine without adding more chemicals into my body. Thanks for asking for a review!
