Report New onset adrenaline surges, tinnitus, and brain zaps. Anyone? in Dysautonomia Discussion Posted July 5 I have had the brain zaps, twitching, and adrenaline rushes at night. It can be related to the position your neck/spine is in when you're lying down. If things are wonky it can impede the flow of spinal fluid to the brain. I see an osteopath on a regular basis and that helps. A tiny dose of gabapentin at night also helps.
