"i switched from pristiq (which i had been on for over a year) to viibryd after my blood pressure went up.  i had some of the stomach issues at the beginning but nothing too bad.  i began with 10 mg, then 20, then to 30 mg very slowly as i had read about the side effects. in all i was on this medicine for about 8 weeks. over this time my whole body basically bloated up.  i looked like i was pregnant!  i gained about 10 pounds and craved carbohydrates.  i was also having nightmares. mind wise i believe i should have been at a higher dose but in the end i opted to change medication due to the stomach bloating. i have been on celexa and pristiq but the stomach component of viibryd seems to affect me badly."
