want2stopgrinding! I feel for you. I have PTSD and am a survivor of domestic violence. I suffer from night terrors, and this has all recently manifested in nightly teeth grinding. It has become so severe that my husband wakes up due to the sound. I wake up with pain radiating from the base of my neck to the top of my head, and my jaw pops when I move it. The longer this went on, I noticed that I was becoming extremely fatigued and, ultimately, dangerously depressed. My husband and I did some research and found that bruxism (teeth grinding) occurs during non-REM sleep....so do night terrors. When hypothesized that my fatigue and depression were side effects of not getting enough REM sleep since I spend most of my night grinding away and awake from night terrors regularly.
I, too, purchased a mouth guard. It helps, but I often spit it out in my sleep. Has this happened to you? Also, I've been taking OTC sleep aids to help reset my sleep situation. This helped initially (2 or 3 days), but now, I'm back at square one....night terrors.
I'd love to keep chatting with you. Maybe, between the two of us, we can come up with some solutions?
Best of luck!!
