Quetiapine
"I was diagnosed with Bipolar One about a year ago and originally took Abilify, until I realized it gave me severe anxiety.  My doctor changed me to Seroquel which I take before bed.  It did take a while to adjust to how sedating it was but it relieved me of my insomnia. However, I have been gaining weight steadily since beginning Seroquel with an insatiable urge to eat about an hour after I take my medication.  No matter what I do to lose weight - 15 pounds gained since Seroquel - I can not lose the weight.  I love the fact that it seems to work well with my body and cures my insomnia, but there's got to be something better for me that doesn't cause me to gain so much weight."
