I can absolutely commiserate - me, too. I have found, however, that sticking close to Primal has helped regulate me tremendously. And, daily outside sun exposure, even if the day is cloudy, as I tend to live an indoors life if I am not careful - totally bookish, I am.
In the end, though, I do believe people are wired with somewhat different internal alarm clocks. Yeah, life and conscious retraining can get you experience in dealing with all kinds of schedules, but I have always been happiest on a shifted schedule, too.
My lifelong best friend (we met in 6th grade and are still going strong in our 40s, even lived together) is my opposite - up at the crack of dawn, turns into a pumpkin at dusk, and is gloriously happy that way.
Joanie hit on a very important point, though, and I have seen this in my hubby as well, that if you hate your job, that absolutely will heavily impact your nighttime activity, routine, and quality of sleep. So how goes it with the job satisfaction??
I have a mantra that I have spouted for years... "If I eat right, I feel right. If I feel right, I exercise right. If I exercise right, I think right. If I think right, I eat right..." Phil-SC
