"i started taking this medication about 2 and a half years ago, and i am now having to be taken off it, just for the fact of it&#039;s not helping me anymore. when i first started taking this medicine it helped me out a lot. i just went through a two and half year break up and fell as it&#039;s just not strong enough. i&#039;m taking 80mg a night, and its just not helping. so i got prescribed pristiq today and now going to see how it works. hopefully it does."
