"i have been on brintellix for 5 weeks. i am feeling more and more like my regular self. my primary issue is gad. i am finding that i am able to focus and concentrate better, my thoughts are not as obsessive, my motivation is increasing. my psych said that i need to give it another few weeks for maximum efficacy. i just hope things keep improving. primary side effect at start up was nausea. but it went away after a few days."
