Personally I stay awake because "men just drop off as soon as they lay down and snore the night away" and it irritates me. Sometimes I purposefully go to bed 15 min earlier than he does and get a head start. My DH worked different shifts for 20 years and can fall asleep anytime or place he desires (and sometimes when he doesn't do it on purpose). If I happen to fall asleep for a few minutes during the afternoon I am usually awake until about 2 am. Ann in Tn
