I took Lexapro for a short period in my early 20's. Perhaps like 3-4 months. I definitely remember having significant brain zaps when I quit. It was a pretty low dose I was taking too - 10mg IIRC. Definitely no more than 20mg. I don't remember the zaps causing me significant stress at the time, but that was primarily because I knew to expect the zaps going in to the experience. Education helps a lot with anxiety. If people know to expect it, and that we are pretty sure that it's completely harmless but uncomfortable, the general anxiety around the symptom will probably be less.

It's different for everyone. I've been on it for over ten years and have never experienced any of these zaps. When I attempted to go off I just got extremely depressed. Never any zap though.
