I get about 3 to 4 hours a sleep before it used to be 1-2 hours sleep then i would wake up at 3 am, awake till about 1 hour, then i feel a bit more tired so i try to get atleast 7-10hrs of sleep so the majority of the sleeping is done after i wake up at in the middle of the night. so probably then sleep like from 4 to 11am.
