So, I’m on my second month of using these plugs and have learned through trial and error what works. Don’t wait until you have symptoms, look at the forecast or alerts and take them seriously. Always wear plugs when traveling from city to city. Look at the data to determine at what level you get migraines. My migraines seem to occur when the barometric pressure drops. Three times I have gotten a mild headache that WENT AWAY, which hasn’t happened for 20 yrs. I used to get headaches that got worse and worse. Also, these are NOT sound blocking and no one even knows I’m wearing them. Today, I wore from 7-11am and 1-3 pm because of the data from the app. I have to sleep on my back if I wear at night for comfort. Every week, I travel out of town and the pressure was so stable last week that I didn’t wear for 3 days. My life is much better without headaches, nausea and fatigue. I have only had to take my sumatriptan once and within 10 minutes I felt fine so I kinda wish I held out. I would much rather pop in the plugs then pop a pill. So, stay diligent and use the information provided by app. I love not going through life wondering how I’ll feel. Finally, the things that I thought were triggers have not triggered anything. For years, people in healthcare have known weather can cause headaches, but there wasn’t anything to use. These have been wonderful and worth the diligence.
