You know the other cool thing, you can simply turn posts off in stream settings to make that stream inactive at any time you wish. If you really do get up at 5:30 am or whenever every morning then that one action is all you’d have to do.
(Though everyone’s in different time zones, for example I believe Jeremy’s in the Philippines. Might have to figure that out. But if everyone around the world agrees to the 12 am-5:30 am or so CST window then there would be no worries.)
