Hi there,
I'm coming off citalopram at the moment too :)
The advice for withdrawing from my physcologist was this:
First 2 weeks: 1 tablet, 1/2, 1, 1/2, ...
Next 2 weeks: 1, 1/2, 1/2, 1, 1/2, 1/2, ...
Next 2 weeks: 1/2, 1/2, 1/2, 1/2, ....
Final 2 weeks: 1/2 every 2nd day.
I start my final two weeks on Friday and it's been going really well. I was afraid that it was going to be terrible but I'm actually feeling better. I think that one of my side effects must have been fatigue / drowseyness or something cause I'm not feeling that tired at all.
She told me that if you start feeling not great when you cut down to the next level then to just stay at the previous dose for a bit longer.
I'm also a bit sleep deprived at the moment .... grrr to teething, but I think my anxiety is alot less now that I'm not a new Mum etc, I have a lot less to worry about then back in the newborn days :()
Good luck
