Brain Zaps Help

I was diagnosed with GAD and was prescribed Lexapro which I used for about a year.  It has been about 15 months since my last dosage.  I can't pin point when I started having them but I get brain zaps almost all day when I think about it.  (The best I can describe it is an electric shock/ a quick shift in my brain.)  This is extremely terrible when trying to sleep as it continues because I can then not relax making it very difficult to fall asleep. 

Alcohol and an occasional benzo (maybe once a month of .25mg) are the only things that seem to relax my brain so they don't occur.  What can I do to stop these?  I'm sick of having to drink to fall asleep at night. (3 shots seem to do the trick) 

Thanks for any help you can give.

I have had brain shivers but not the zaps.  I have always done a very slow wean off of any of the SSRIs under my Drs. supervision.  I  read that Omega-3 may help to ease them, but as always, no one really can support that with facts. I did use the fish oil myself and felt it was helpful.

I hope you soon get past this nasty withdrawal effect. 

Kindly,
