"i have been on this med for only 4 days after being on multiple other meds for general anxiety disorder for several years now. and i can already feel the difference in myself. not exactly where i want to be yet but definitely positive results so far. it does make my pupils seriously dilated and at night when it&#039;s dark my vision seems like i&#039;m on a merry go round if i moves my eyes to quickly. other than that i feel much better than just a few days ago! hopefully this med will work for me. i hate switching meds cause of the time i have to wait to start a new one. sends me in a downward spiral of panic attacks and irritability. so far since being on effexor ex i&#039;ve not had even one episode!!!!!! and i was having them every single day!"
