Lexapro Withdrawl Symptoms? Please HELP!!

Hi everyone! I haven't been around in quite a while, but I am so glad to have rediscovered this wonderful forum.

SO....I have been taking lexapro for the past 5 years...10mg for a year, then 20 for 2 years, then back to ten up until the the beginning of the summer. I really felt that it was the right time to come off of it. It had helped me so much with my panic disorder and I have worked through alot over the past couple of years. I began to taper off in may or so of this year, very slowly. I had the "brain zaps" for a week or so, but nothing i couldnt handle. Over the past few weeks, I got down to taking 5mg every 5 days. My doctor had told me that the worst parts of the taper are over and that it was safe to just stop taking it. So last Saturday I took my last 5mg dose, and I have felt great...until last night. I had horrible insomnia, which I have never had before, and today at work i was so jittery, not anxious or panicky, but while sitting at my desk my legs would just not stop moving all day long. Also, i am extremely irritable. I have been researching withdrawl side effects and all of these things seem to be normal, but how long will they take to go away? has anyone else here had any side effects from tapering off? I just need some reassurance that this will go away! Please help!!!

With Love and Hope,
Leaves
