Hey guys, I almost feel silly posting this bc I feel like I cant explain this well....So in the past I took SSRI medications for anxiety and would get "brain zaps" (https://www.anxietycentre.com/anxiety-symptoms/brain-zaps.shtml) when Id go through withdrawal.I haven't taken these meds in years...But I am getting that feeling over last year or 2 only at night...and periodically. It only went away when I took hydroxyzine for high histamine and anxiety but I stopped taking months ago. It also feels like I get a quick feeling of light headedness or a startle feeling. Like almost when you are super tired and almost falling asleep. I notice that this happens when I wake up from a deep sleep in middle of night and then I feel my heartbeat strongly and get this zap/light headed feeling/startle that lasts like a second and only goes away when I am completely awake. I feel this mostly in back of neck and head...like a subtle rush. Im really frustrated bc I dont think Im explaining this well 
my fear is that this is a sign of a neurological issue such as ALS, MS or MSA. Or a heart condition. Last two weeks I have noticed more heart palpitations/flutters and zap type feeling happening more frequently specifically at night. My wife listened to chest and says heartbeat sounds completely normal.
Only difference is that 2 1/2 weeks ago I started taking Chinese herbs through herbalist. I worry about my health a lot but I am very fit and eat fairly well. Any thoughts folks? thanks
