I had brain zaps for 2 weeks straight after stopping Lexapro cold turkey. I kept getting zapped every 5-15 minutes. It was awful.
I ultimately asked my pdoc for another Rx of Lexapro because I couldn't handle the zaps. He told me to cut the tablet in half and take a tablet every other day. Worked like a charm.
As long as you don't go cold turkey, you *should* be okay. But if you do start getting brain zaps, ask your pdoc to titrate your dose slower, and consider taking a tablet every other day until you stop getting brain zaps.
Best of luck
