I am resetting my biological clock. I am studying for Step One. So I am going to bed early and getting up really early, so when I show up for the test, in the morning on test day, the time of day seems optimal for my brain functioning. So at this point, I get up at 6am, have some coffee, and start kicking ass. I am asleep at 10pm. I spend 90 minutes each day working out as hard as I can. I eat really healthy. Sleep, eat healthy, work out, study. Go to bed early. Get up early. Drink coffee and go for it.
