Olanzapine
"Olanzapine is great for bringing down a manic episode but can hinder recovery as it made me feel so depressed.  On 2.5 mg and going to come off as it makes me so low and depressed. I sleep  for about 15 hrs and have no interest in anything.  It's helped with my anxiety but would rather feel anxious than live with the depression I am counting down the minutes till the day is over. Previous have done this and have felt better within days, longest I've stayed on it this time but also longest I've felt depressed. Will let you know how I get on"
