I have got to guess that someone knows what I'm talking about here. I am on Cymbalta and if I forget to take them, obviously I get brain zaps. I may forget about once a month, I tend to go to bed early when I'm upset and sometimes it slips my mind. Now I want to get off the Cymbalta, but I'm not looking forward to the full body zaps that will be coming. Does anyone know how long they last after you stop taking them? 120mg for almost a year, I have recently been taking only a half dose for about a month, no zaps with that. I want to get on a smaller dosage to come off it. I can't do the sudden downs anymore and it isn't helping with pain or any other symptoms I have, rather it stopped. If its not helping I'd rather not take any of them. The zaps btw feel like momentary fainting spells in case you need a description.
