Hi I have been on Citalopram for a year, but keen to come off it as I have been feeling much better. Cut down to 10mg from 20 just under 3 weeks ago, and I feel lousy. Am getting horrible headaches, I can't stop sleeping, and feeling irritable and panicky. I thought if I came off them slowly I would feel ok, so I don't know why I feel so bad. Can anyone advise please?
