"i tried taking pristiq for 6 days.  the side effects were so bad i could not function.  i could not work, eat, or sleep and felt nauseous. my vision was blurry. my mouth was so dry and my appetite was non existent.  i only weigh 111 lbs and i do not need to miss a meal.  i have stopped taking this medication.  i was taking 50mg and this is the first medicine i have ever taken for depression.
