"i&#039;ve been taking effexor xr for almost a year now! i suffered from post partum depression! i&#039;m about to be 28 and had only taken an anti depressant back when i was 16 for less than a year. negatives when starting effexor for me were insomnia and loss of appetite ! my doc prescribed me a low dose sleep aid and after 4 months of taking effexor i no longer needed the sleep aide! i&#039;m currently on 75mgs and i&#039;m productive, happy most days, and no more panic attacks that are unmanageable. i even gained my weight back !! this medication isn&#039;t for everyone but it worked for me! negatives i still experience every now and then are rapid heart beat, hard to concentrate on one thing, and sometimes too much energy but can be levelled out with exercise!"
