I have been taking 15 mg of Viibryd for almost three years. I was just taken off Viibryd. I started 5 mg of Brintellix yesterday. (Within an hour of taking the med, I had a pounding headache.) I'm switching meds because too much Viibryd caused weight gain and too little didn't truly help my depression and anxiety. Either way, the med killed my sex drive. I'm looking for positive, constructive feedback about Brintellix. Thanks.
