I have been on citalopram for three months, and initially the main side effect was insomnia, for which I took lorazepam (which I had anyway to counter panic attacks at the time)
Psychotherapy has been excellent for building my resilience and giving me coping skills, but I think the citalopram has helped heaps as well, and I reckon I have only just started feeling the positive effects. I am on it for general anxiety disorder, not depression specifically - although I was having depressive symptoms which are all but gone now!

My doc recommends six months at least before weaning off.
Yes, its that sensation that 'I feel like myself.'
Nightsky, interesting about the first couple of nights...the first night I took it I had similar symptoms and TOTALLY freaked out...went to the ED in an ambulance as I was convinced I was going to die.

But it was just a major panic attack. I have never been on any meds before in my life, so it freaked me out...
