I was on cymbalta for anxiety/ dizziness and it sropped working. My dr.had me take 50 mg.Wellbutrin for a week with the cymbalta. I stopped the cym. a week ago and upped the W. to 100 mg. I have still been dizzy but the heart palp is better. I now have a sick headache that nothing takes away. Any input from someone that has been on it longer?
