Fluoxetine
"So I was previously on citalopram and it reduced my depression but made my pmdd more noticable. A psychiatrist recommended prozac as citalopram is not effective for pmdd. The month that they weaned me off citalopram and onto prozac was HELL.

 Now I'm fully taking prozac at 40mg it is working already, I have more energy and can get up and do things more often. I've not had a period on my full dose of prozac yet so I'm not sure how it will work then, but from what I feel now, I think it will be great. 

Side effect: I have incredibly vivid and unpleasant dreams (but had that on citalopram at first) and they are so vivid I often confuse them with real life momentarily. I also have bruised and itchy legs."
