Brain Zaps

Has anyone experienced "brain zaps" --- I have experienced this sensation several times in the past few months.  I have been describing it as brain spasms but when I goodle brain zaps it appears a lot of people have them.  Seems to coincide with coming off SSRI's which I have never taken.  I am having an EEG on Thurs because I am worried it may have been a mild seizure -- now im not sure.  Does anyone know about these things>

I have been having what I think can be described as that.  Kinda like a wave of sensation that goes through your head?  It happens really fast.. without any real pain, just kinda funny feeling.  I notice them when I am trying to fall asleep mostly.  Is that what you had?  Did you find out what they are?

I've had these before, for me it was definitely from coming off Lexapro.  I was prescribed Lexapro for anxiety, tried it for awhile, and while it semi-controlled my panic attacks, I didnt like the way I felt on it, so I stopped.  When I started getting the "brain zaps" I did some research and figured out that it was from the Lexapro withdrawal.  They lasted for a few months - 3, maybe?  I dont get them anymore, but now I get weird adrenaline rushes for no reason at all and I'm dizzy almost all the time.  I never felt bad (besides the panic attacks) until I went on Lexapro, now I feel like all of this is from the drug.   I just feel like a completely different person.

I havent had them for a while.  I did have the EEG and it was normal and I also had an MRI which too was normal.  I hope I never get it again but its almost 2 years later and I still dont know what it was.
