"viibryd  is working well for me.  i changed from celexa to this drug due to not being effective anymore.  initially it did give gi issues for about 4-5 days but then eventually went away.  viibryd does has the least sexual side effects than the others. my dreams are pretty vivid with occasional well, i say not so pleasant dreams.  i went up to 40mg along with 300mg lamitcal and 30mg nortriptyline.   the viibryd makes me a lot less sleepy than the celexa did.  so far all is well."
