Hello,
I started taking 20mg in March 2012 and I am still on it now. I had seven months on 20mg, where I was making progress every month and feeling better all the time, but then a wee relapse occurred, so I was put up to 40mg in October 2012. 40mg worked so well for me and just made me feel like I could do everything I wanted to do in order to get "my life back" and I did not even realise until starting to take Citalopram and receive talking therapy that I had not been "right" in myself since my first pregnancy which began in summer 2007.
I had been on 40mg from Oct 2012 until this Spring when I got myself onto 20mg. I am pleased to say I am coping perfectly on 20mg and that has been about 6 weeks now.
I would be quite happy to be on this wonderful drug for the rest of my life, as it just makes me feel normal after such a long time of suffering with PND and anxiety, but if I can completely come off next Spring, then I shall know I am completely better. I say Spring as my GP says reducing dosage is easier in Spring or Summer due to sunshine being more available and I believe this to be the case.
Side effects for me were minimal: dry mouth, nausea, thirst and constipation at the start. The nausea was only for about 3 or 4 days. The dry mouth and thirst for about 3 weeks and the constipation for about a month. When I increased from 20mg to 40mg I experienced about 4 days of nausea and that was it. Also, when reducing from 40mg to 20mg recently, I only had a tiny bit of nausea for about an hour the day after. I reduced slowly, though, which maybe helped. I took 40mg one day, then 20mg, then 40mg, then 20mg, and so on, for about two weeks.
I always take mine first thing in the morning at breakfast time. ADs are necessary for some people at some points in their life and noone should ever feel ashamed or worried about taking them.
