i can relate...i used to work overnights, and my sleep pattern was interrupted (my circadian rhythm was thrown off) ....it's sooooo difficult to sleep during the day when the rest of the world is awake and bustling around, and the sun is shining all bright and sunny.
if one must work nights it's perhaps a good idea to invest in room darkening shades/blinds, and claim a "sleeping room" that is quiet, away from the hub bub of the household, that can be associated with "winding down" and "sleeping".
In the meantime, have as many pray for you as possible.
