Any suggestions on how to stop brain zapping that wasn’t caused by meds?

I suffer from GAD and was working a very stressful job when I “crashed and burned “. Started having respiratory issues that progressed to symptoms similar to an anxiety attack ie: heart palpitations, jerking limbs, etc.

I ended up having to leave my job and was laid up on the couch for two weeks with no appetite and difficulty sleeping.

I started getting brain zapping before I even started taking meds to deal with this. It would happen over and over again as I was trying to fall asleep and eventually I would end up being awake all night. Have had to take different drugs to deal with this since mid December. Have a terrible time with drugs side effects as I am really sensitive to just about Eve I have tried. Am now on Klonopin so I can sleep but even .25 mgs I wake up super dopey and have no appetite. Anyone have any suggestions on ways to get rid of these zaps with supplements or natural methods? Sick of being on drugs.
