Hi arcadia - gosh that sounds a bit frustrating. GPs seem to vary so much. Some have their bug bears about certain drugs - doesn't help us patients much does it!!
I think citalopram is the AD of choice for GPs. A psychologist friend of mine rather cynically told me it was because it was cheap (whether that is true or not I don't know).
It's a shame you can't get referred to CMHT then you would get to see a psychiatrist who is much more skilled and knowledgeable about all the different ADs (and there really are LOADS of them!)
I can see why they wouldn't much appreciate self-prescription, but actually you weren't doing that, you were really just asking her advice about whether it could be suitable for you. I am no doctor, but much of what you've described in other posts rings so many bells with my experience, and mirtazapine really has been the best thing for me. Citalopram was the nail in the coffin for me in terms of being admitted because it sent my anxiety sky high and made the insomnia so much worse.
It's good that your sleep has improved a bit again though. I really think it will sort itself out over time. I never thought I would sleep properly again after everything that happened to me, but I do now. It's good the nytol is helping, I never found that one particularly helpful.
One thing that helps me, don't know if it will you, but here goes. When I get into bed I play out in my head the same "story" every night. This is going to sound a bit weird but basically I imagine I've been travelling on a very long journey, and it's time to stop for the night. I am in a forest by a river. I unpack my bag and in it I have a thick grey woollen blanket. I imagine laying out the blanket, choosing the right spot, by the river etc. And play out to myself all the details e.g. how tired my legs feel, the sound of the river, the warmth under the woollen blanket. I embellish with as many details as I can, and then eventually - usually - I fall asleep!
I'm not saying this would have particularly helped when I was really "ill" as I believe that was a chemical imbalance. But it helps me now that I am just left with a kind of residual "anxious" insomnia IYSWIM? Anyway! As you were!
