"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&#039;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&#039;ve stayed on it this time but also longest i&#039;ve felt depressed. will let you know how i get on"
