Yep, score 53, intermediate here. I need at least 90 minutes or so to really get in my morning groove. My peak hours of alertness and energy are about 10 a.m. to 6 p.m. I wake at the same time regardless of bedtime so I have to make myself go to bed earlier or I will be tired. I went to bed about 10:15 last night and had to wake up at 5 this morning for a morning appt. an hours drive away and it is now 12:30 and I am wiped out.
The time change has really screwed me up the last few weeks and I am having a hard time getting to bed before 11–11:30 lately.
I am going to bed at like 8:30 tonight, I need to catch up on my sleep after a busy and moderately sleep deprived week. I need a 9 hour night to feel optimum and if I run on 7 hours for a few days or a week I feel run down. I am not a napper at all, unless sick.
I never shake off the grogginess so I prefer to just go to bed early over napping.
