"I have been on celexa for 10 years now.  It was no longer working for me.  My doctor cut my celexa dose in half and had me take 5mg of Brintellix.  I read all the reviews on here and was hopeful.  Many talked about nausea, so when I experienced nausea after 20mins of taking the meds, I thought it was normal.  A half hour later, I was on my way to work with my kids, I threw up all over myself in the car.  I highly recommend trying this drug for the first time on a weekend. Didn't work for me :("
