I've been doing the early rise for 30 years now. We both start work at 0600 so gotta get the morning chores done.I can't imagine 3:30 every day! When my husband was working, 5am was too early for me, but we did it for probably the last 30 of the 35 years he worked at the dams! I do however wake up early every once in a while, especially if I've gone to bed to early...part of it is my achy body just can't stay down any longer! I ran on 5 hours of sleep for many years, now I can sometimes get 7, so that's an improvement!
