"i started taking 20 mg as i was taking 20 mg of lexapro. at first i felt better than i did with lexapro (after 15 years on lexapro the side effects were to much) after about two weeks i started getting more migraine headaches than i was before also i was starting to get heart palpitations and these problems increased with time. the migraines got to the point i was having one daily. viibryd also caused me to be impotent even when using cialis, the migraines likely contributed to this. i told my doctor about these problems and he told me to stop taking it. i have taken many drugs and viibryd is by far the worst drug i have ever taken. i don&#039;t think it is fit for consumption by anyone or anything. i took viibryd for almost two months."
