+1 on that sleep thing. My wife insists on speaking with me late at night. I managed to get off the phone before 10 last night, then I get a call at 10:30 from a cousin, 10:45 from another cousin, and 11:05 text from a friend. I just shut the damn thing off after the last one. I need at least 7.5 hours of sleep to function normally the next day.
