I've just finished my first two weeks on Viibryd. I've noticed with the 20 mg dosage that about an hour after I take it, I start having horrible irritation in my lower legs. My husband said it sounds like Restless Leg. Has anyone else experienced this? I start my 40 mg dose tomorrow and I'm terrified of what is going to happen. My legs are so irritated that it's borderline painful. It's really hard to describe... The side effects from week 1 at 10 mg went away fairly quickly but this leg thing that started at 20 mg is showing no signs of letting up. I've been bounced around on so many different Rx's that I'm hesitant to change again because Viibryd is actually helping my anxiety/depression...
