I've been on 30g citalopram for about a year now and over the past 6 weeks have been slowly reducing to 20mg. I am fully on 20mg and have been for about two weeks. Now I am having terrible pmt not the anxiety kind but the sore breasts and cramps and I'm not due on for 12 days. I usually only get this 5 days or so before I'm due on. Can this be a symptom of the reduced dose? Can it mess with your cycle? Thanks in advance. X
