What does Seroquel actually achieve?

I deliberately say achieve. I am sure there are numerous studies about what it does in "med speak". I am not too concerned with what it does to various parts of the brain. I am concerned with how I feel when on Seroquel.

In the honeymoon period, I guess I was blinded by the improvement in my sleep, but what price sleep? My mornings are a constant struggle, anywhere from general anxiety to depression. I very rarely want to get out of bed. If I manage to get up, I have no motivation to do anything. I am writing this just after noon. I couldn't have concentrated well enough until very recently. My evenings and often my afternoons are a different picture to my mornings. I feel like a different person. I suspect Seroquel because of my experiences last year. I reported to my doctor that I had the anxiety. The response was to increase my dosage from 100mg to 200mg and then to 400mg. The anxiety increased and I returned to 100mg, my current dosage.

What about the anti manic properties? I recently had a 7 or 8 week period of hypomania. I took my Seroquel regularly throughout. The only effect that I noticed was that I was physically impaired longer than I was sleeping. I was only sleeping 2-3 hours each night. I don't think the Seroquel did much for the mania.

I am beginning to wonder if Seroquel is causing more problems than it solves. My sleep is erratic. My mornings are a nightmare, And then there are the incessant dreams and disturbed patterns of dreaming. Does anyone else share my concerns?
