Essential Calm is amazing! For over 2 and a half years, I have been dealing with excruciating neck pain that was making it difficult to sleep. Just laying down caused a massive headache. I could barely turn my head. I was constantly uncomfortable. I've been through many months of physical therapy, Xrays, MRI's, CT scans, multiple injections, medications, weekly chiropractic, bi-monthly massages, weekly acupuncture...but the neck pain wasn't getting better and my migraine headaches were increasing in frequency, duration and intensity with no relief. I've seen orthopedic surgeons, neurologists, neurosurgeons, been to pain management... The headaches and neck pain just kept getting worse. I was having more days with a migraine than without and dreaded going to bed. I discovered this product while scrolling on Facebook and was immediately skeptical, but I was willing to try something different. What did I have to lose?? I honestly didn't think it was going to make a difference. But, it did the first time I used it!!! I haven't had a migraine in 25 days, I can turn my head and laying down no longer causes a headache!!! I keep one at my desk, one by my bed, one in the bathroom to use when getting dressed and getting ready to go to bed. I've shared it with friends for their back pain. I take it with me on trips. I am thoroughly amazed and so grateful to have found this simple product!!! Thank you!
