I was on citalopram for a few years, including during my last pregnancy. Even on the highest dose I never had any problems. I know that with a couple of other drugs tho I had problems e.g. Prozac. I tried it for 10 days then had to change. Is there any way you could keep trying with the citalopram for a week, so that your body can adjust to it or are the side effects too much. It often takes a while before these drugs begin to take effect in our system...GL
