Hi Discogirl,
I was on citalopram for a while about 7 years ago. No problems with sleep at all.
It was great for getting rid of the awful down feelings - but for me this came at the expense of normal natural highs. For example, when I was with friends and I'd laugh about something it was a just a physical laughter response - I didn't feel the positive emotions but knew intellectually that something was good. It flatlined my emotions - no lows but no highs, and I missed the highs because I used to have loads.
I also responded to people differently. Previously, if I was a bit annoyed at someone I'd keep it to myself but on citalopram I really told them! This didn't always have positive results, and looking back I was quite brutal on occasion. Not like me at all, but on citalopram I didn't care and just said what was on my mind - no emotions and no common sense filter.
This was only my experience - I have friends who swear by SSRIs, and they don't go around offending people! I'm mentioning this because I wish someone had told me this was a possibility before I started on citalopram. I lost friends at that point in my life and unfortunately I can't get them back. So maybe keep checking every week or so to see how you think your interactions with others are going, or ask a few friends to keep an eye out for you.
I hope you find it helps you, I know of several people who believe citalopram is the best thing ever!
Caroline
