I go bed when I get tired and that could be any time day or night. I sleep for about 1 hour and then I'm good to go for a while longer.
I get about 3 hours sleep a day this way, 4 hours if I'm very lucky, and this was even with taking Zopiclone and Trazodone for sleep.
Now I have stopped taking those 2 drugs and sleep about 1/2 to 3/4 hour per time.

It's a good thing I have the Internet to keep me busy because it really helps to keep my mania and deep depression at bay.
