"i have found all these comments really helpful and reassuring. i started taking pristiq yesterday and it is the first antidepressant i have tried. after taking my first dose i felt very groggy/tired but i had trouble sleeping last night and had frustrating, repetitive dreams when i finally got off to sleep. today i have taken my second dose in the morning so that hopefully i can sleep tonight. so far i am not feeling drowsy today and i have been feeling good emotionally. i am optimistic about this treatment and love all the positive comments."
