For the past 6 months I’ve been sleeping so much and I’ve been constantly drained and it’s to the point where my boyfriend started timing my sleep and I’ve reached 48 hours straight of just sleep, during that time I woke up to eat for an hour and went back to sleep. 

Im wondering how does bipolar affect sleep and if it has something to do with it? Because prior to the 6 months I would be hypomanic almost everyday and it switched after I added an extra medicine (latuda)

Is it because of the medication or is it a bipolar symptom?

Note: I used to take seroquel XR 200 mg + cipralex and now I added latuda
