I just HAVE to add my story here!! I was on Lexapro 20mg for 2yrs...

Whew not alone on this one either! I barely tappered off before I just stopped cold turky. Wanted that crap out of my body. I pretty much had the side effects you described while on them, but getting off them were you extremely tired to the point where you did not want to be social whatso ever? I cant even get up to go to work at times. Its only been about 2 weeks, but Im just praying that there will be relief soon.

OMG! I am so happy to hear that I am not alone. (I'm sorry I don't mean that about you having to go through it). I have been trying for a few months to get off of the lexapro. Sadly I was only on it for a few months to begin with, when I realized that I couldn't cry, I simply had no emotion. That really bothered me, because if you knew me before they called me "crying Tracy" lol.
Anyway, I gradually lowered my dosage until I thought ok I won't take anymore. About 4 days later I started getting these internal tremors, and cold chivers. I thoughtI was getting sick. I talked to a nurse that I work with and she told me that it was part of the withdrawal symtoms. So I decided to take a 4th of a pill and low and behold the tremors went away, only to return in a few days. This has lasted for a long while and now I am at the point where I am not taking any pills, but I still have the tremors and the cold shivers. I hate it and I pray that it goes away. My mind is like the early stages of Alzeimers and that is really scary. I lose my train of thought constantly. I can't remember simple words while I am talking. I too hope that someone reads this before they decide to try lexapro. Don't get me wrong, it does work for panic attacks, however my panic attacks are far less terrifying that the side affects of the lexapro.
Thank you for posting this information, I feel much better, although I hope the tremors stop too.

Yes I wondering how long did the withdrawl symptoms last. I am pregnant so I stop taking the Welbutrin and the shock waves are really bothering me.

How many mg were you taking. I am taking 20mg and have tried to ween off of them. I was absolutely miserable and dizzy. Brain zaps like crazy. I want to go off of them but HATE the withdrawl symptoms.
