I had some vision problems coming off of cymbalta. It was weird--blurry at certain points of my field of vision, and kind of like looking through a stained glass window.
It varies from person to person, but by the end of my fourth week of withdrawals, they were pretty much over. I still had some fatigue and mood swings, but that was it. I do have to say that I'm so grateful it's "over". I'm at day 36, and am sooooooo glad to have this crap behind me. It was so damned miserable. So now that my days are mostly good, I can look back and sigh with relief.
For those still suffering, just remember that it CAN be done, and IS being done by many people. There is "the other side" to this, and YOU CAN GET THERE!!!!
