I started on 5mg of Brintellix and since have had a stuffy nose contiuously. That was over 3 weeks ago. Then I started having bad dreams like one where I die or me and my husband divorce one it was 9/11 and I was in one of the WTC buildings as they fell! I'm afraid to sleep! My dr increased it to 10mg and it's helping for my depression but the stuffy nose and bad dream are hell. Also very hard to wake-up and I have a little bit loss of balance at times. The nausea can get real bad too and I'm in the bathroom a lot.
