"i&#039;ve been on viibryd for a year now. start up symptoms were upset stomach, diarrhea, and nausea. i got to about 10mg for a week and couldn&#039;t handle the nausea. so i backed off to about 5mgs. i had a good improvement and nausea went away. tried to go back up to 10mg and by the 4th day i had the same results. keep in mind anti-depressants are very powerful.  i had improvement from just 5 mg. my doc wrote me a script for 20 mg and i cut those into 4. i still have days where i don&#039;t feel well, but it has decreased my depression symptoms and panic attacks with minimal side effects. i gained a little weight about 7 lbs. no sexual side effects. has to be taken with food."
