"i&#039;m 45 years old and have lived a pretty normal life except for my occasional heightened anxiety. recently, my anxiety and panic attacks had escalated out of control. i was feeling out of touch with reality and having multiple panic attacks a day. unfortunately for me, after 2 doses the effexor caused mild hallucinations; light pixelating and things moving in fast motion. it was adding to my anxiety so i went off immediately and the hallucinations went away."
