"i started taking pristiq about 3 1/2 weeks ago to help with stress and anxiety.  i have had mild headaches and a little bit of nausea. i immediately feel sleepy when i take it so i am taking it at night before bed. i do think that i am sleeping more through the night than before. i have tried a few other medication&#039;s such as zoloft and prozac.  i felt very sedated, no sex-drive, wanted to sleep all the time (before kid&#039;s) really could not even cry if i wanted to.  i also gained 40lbs which made things worse.  i am still questioning myself if i really need medication or just accept the fact that i cannot have a house with everything in place with young kid&#039;s and that not everyone is going to be as kind as i think they should."
