I was given seroquel one time for anxiety, and when it kicked in, my first impression was "why don't my legs work?" I couldn't walk! It was a scary feeling, and instead of feeling calmed down, I panicked.
My sister was prescribed seroquel during her first detox, and it made her incredibly sleepy. She didn't like how it would make her feel, even hours after it was supposed to have worn off.
Yet one other lady who was a friend of mine swore by the drug. I guess it depends on individual body chemistry, temperment, and which phase the moon is in, lol!
I hope that whatever happens with Seroquel that your daughter will have a bright, happy life ahead of her.
