Hi there- I was on paxil 40 mg for over a year and then went down to a lower dose (can't remember) and I had a slight case of the zaps and a numb type feeling in my lips and finger tips. I eventually went off of it completely and both things got a lot worse- made me want to go crazy. It seems like it was about two weeks, maybe even three, before they went away completely, but they did. I guess it has to all get out of your system, just like they say it takes 2-6 weeks for you to notice a difference when you start taking it. It is probably the same thing with getting it completely out of your system and since your body has gotten used to a certain dosage every day, I guess it might go a little haywire. Hope this helps some, but just be patient and it will go away.
