Firstly from your mail and your drug doses and side effect profile , I m not sure that you have been diagnosed properly or not and need to know who have diagnoses you , I mean a psychiatrist
or a general physian...as diagnosis of bipolar with schizophrenia
is one of very rare disorder.
Secondly there has been no mood stabiliser in your prescription , thirdly even at 5 mg of olanzapine
you are having such sedation...I would suggest you to take a second opinion
about reconfirm your diagnosis once.
If your diagnosis remain the same and you continue to be on same medication than you can decrease your dose of olanzapine which is the main reason of sedation and cause secondary dizziness
the whole day
