"i&#039;m 16 and have been on fluoxetine at 40mg for about 8 months now. it works amazingly for me. i don&#039;t break down every night and i don&#039;t sleep for 15  hours anymore. i still have this weird feeling in me that kind of misses the way i was before the medicines, but i don&#039;t think that has to do with my medication. i do have one side effect though, i have had tremors in my hands for about 5 months."
