I was on Citalopram and had more problems on it then when I had (abruptly, without Dr's or family's knowledge.. heh) stopped taking them! Everyone said they saw a "good change in me" but really the only change inside of me was I had gone from miserable to just numb and felt nauseous the first few hours after taking them... so basically I wasn't sobbing and having panic attacks (I was prescribed them not just for depression but for anxiety) which was an improvement to the people around but a horror to me because I just wasn't feeling anything. I'd personally rather feel bad than nothing at all. What's kind of funny about it is no one believed me when I told them I'd stopped taking them for at least 3-4 months until I displayed the full bottles of pills that I'd still had.... shows what difference it made in me, eh?
I fortunately, did not have the shocks too bad. I think maybe once or twice and they were mild and I didn't know what they were until long after when I read something about it online. I wish I had advice on that but I don't really. I just thought I'd chime in that I wasn't a big Citalopram/Celexa fan myself and good luck with the weaning
