I would go back to my pdoc if I were getting that little sleep and still having hypo symptoms.

It may be that you don't need as much antidepressant now. Your pdoc may be able to lower the dosage and then your hypo might be lessened. Just a thought. Bipolar is like a pendulum, swinging from one drastic mood to the other. With proper medication, the swinging becomes less drastic, hopefully.

Some people say their hypomania turns into mixed states (mine does often). Mixed states includes agitation and anxiety for me as well as some mild depression. I'm a rapid cycler, so you may be different. Mine cycles pretty rapidly from one mood to the next, and I thankfully don't have a big "crash" into depression. I also have times of feeling stable/ "normal." I wish I could feel that way all of the time!!
