I saw your comments on my earlier post in 2016 about Hypnic headaches. While Emgality and Avovy had both helped prevent migraine headaches from daily to "only 4-5 per month," neither has had any impact on preventing my noctural "hypnic" type headache. My nighly nocturnal headache were finally diagnosed in 2007 as a "hypnic" by a Headache specialist, in CA, I saught help at Mayo clinic in 2020, and learned it no longer fits the category definition of HYPNIC. But it is an Inflammary style headache that mimics a cluster headache, occuring 4 times nightly at REM cycle, if I don't take Indomethacin plus caffiene (and now also Melotonin). I also must take RX pantoprozole to prevent GI bleeding from long-term use of Indomethacin. My life is FAR BETTER now that prior to finding Indomethacin (started with 75mg ER , and took that for many years) and Caffiene. I drink 1/2 cup DARK ROAST coffees about 30-45 minutes prior to bedtime. I used Starbucks Dark Roast Italian nightly for years, but have switched to Great Value (Walmart) Dark Roast Italian or Columbian (both also work and taste great) to save $$$. My Indomethacin dose is now lower than it was initially. I now split a 50mg dose (25mgs 1 hour prior to bedtime, and another 25mg AT bedtime along with 20-30mgs melatonin). I hope you can find something that works with few if any side effects.
