Hello, I started on citalopram last year. I started on 10 mg, and took it in the morning, as I found it disturbed by sleep if i took it at night. I had about a week and a half of feeling rubbish on it, a kind of unsettled nauseous feeling in my stomach and some awful panicky dreams and frantic feelings in the middle of the night. At one point I though I was going to stop taking them, but then it stopped and they kicked in.
I have found them brilliant, I double my dose when I am starting to feel feelings of being overwhelmed, and also when i get pmt (which causes me to get really down). But I have never had to have more than 20mg.
Before i took them, i was getting extremely down, not wanting to see friends, being extremely short tempered with our dcs, and somedays just felt so overwhelmed by everything that I just couldn't get through even the most mundane tasks. All that has gone, and i just get on with stuff. My main worry was that i would feel like a different me, or would seem different to other people, but I feel the same, and dh assures me i am the same. I also didn't want to stop feeling things, but I still cry and feel worried and sad, but those feelings don't engulf me and stop me functioning.
Hope you get on ok with them. If you don't, ask your dr about alternatives, i had a friend who really didn't get on with them, and switched to another ad which suited her much better.
