"i am 33 years old and have been depressed for as long as i can remember. this year i took the leap and accepted the fact that i need medications to continue living a functional life.  i was prescribed 20mg celexa once a day.  for the first two months things were getting better i did experience some insomnia but that subsided after two weeks. i eventually plateaued and was given a new dose of 40mg.  not sure how much it has helped, i constantly feel tired and lack motivation.  i will looking at other meds when i see my doc next."
