"i am a 21 year old female. i was on prozac for ten years (40 mg at the end) before switching to effexor (37.5 mg at first, 262.5 mg now) because i was having issues with anxiety. i was ok for a while then i became extremely depressed and suicidal. my doctor increased my dose and although it did take away the misery and suicidal thoughts, i wouldn&#039;t describe myself as happy. i feel constantly tired, sleeping up to 16 hours a day. i can&#039;t work and social situations exhaust me. it took me a while to realize effexor might be responsible for some of these symptoms. i am talking to a psychiatrist about changing my medication but i&#039;m very worried about the infamous withdrawl from effexor."
