Where the heck do you go to school where you can get to the gym before and after school?
The only thing I can figure is that you are still in your didactic phase, because now that clinicals have begun, I am up by 5 to get to the hospital on time, and when I get home, I have anesthesia plans to write, studying for classes to accomplish, and, oh, sleep in there somewhere. You may be in clinical for only 8 to 10 hours, but I swear, when you come home, you are just exhausted.
Seriously, at least in my case - and the case of classmates and the other SRNAs I know, once clinicals started, all bets were off regarding any semblance of schedule and routine.
Exercise and fitness are crucial to maintaining your health and sanity during anesthesia school, but understand that you can't get something for nothing. I'm getting up at 0400 a few times per week to stick to my fitness goals. The tradeoff? Caffeine is now a physiologic necessity for cerebral function!
