"i had been on lexapro/celexa/citolopram for the past 10 years (maybe a couple more) and it was fabulous!  about a year and half ago it stopped working for me.  i had tried wellbutrin before the l/c/c and it was horrible for me - like wanting to hide in a corner under a desk paranoia!  my doctor sugested viibryd after the l/c/c stopped working and so far so good.  i can&#039;t attest to the gi problems, and i don&#039;t know if i have the night time issues (i sleep like a log and am single so no one is there to tell me what is going on while i&#039;m sleeping).  i do have sleep issues, but not related to viibryd.  i have found that the viibryd doesn&#039;t help with anxiety/anger issues, so the doctor suggested adding l-theanine and that helps tons!"
