"i have major depressive disorder. i was put on lexapro, the side effects were unbearable. i got switched to prozac dosage got switched for a couple of months and then got put on sertraline, became suicidal. i gave up for a year on medications and tried exercising but still had bad depression and was tired but couldn&#039;t sleep at all. now, i&#039;ve been on pristiq for 9 days and some days i&#039;m in amazing moods and some i&#039;m really quiet and still have trouble sleeping but these reviews help me not want to give up yet. thank you!"
