major depressive disorde
"I started on 10mg of Brintellix about two weeks ago after being taken off of Wellbutrin and Celexa. Right away I started to feel physically ill. Horrible headaches, sour stomach, extremely agitated and tired. I don't know if it's withdrawals from the other medicine or effects from starting the Brintellix. I am leaning towards the latter though. I just took my medicine and only an hour later I am feeling very ill again."
