"i have just started taking saphris 5 mg in the morning and find that within an hour i&#039;m exhausted and need to go back to bed most of the day! not happy with this and am wondering whether it&#039;s best taken at night? i was diagnosed bipolar type 2 a few months ago and am on lithium , seroquel (which i&#039;m being weaned off), mirtazapine and lorazepam as needed. thanks."
