Can someone help me? I started waking up with migraines mid-sleep in Jan 2019. Happened once and then a few times summer of 2019 until Dec 2019. Then it’s been happening 1x month since June. I don’t know why and I don’t know how to prevent it. Any suggestions? Can it be clenching/grinding? Sleep position? I’ve had migraines for 20 years and this is all really unsettling. Thank you. I want to know what can suddenly be causing this. I started Botox 7/28.
