Beside the standard “these are necessary preparation days for Rosh Hashanah” you should know that I notice you’re not alone. Look around during these two weeks and you’ll see that many men who you meet seem to be sleep-deprived.
So the best chizuk I can afford at this time is probably “you’re in good company with the rest of K’lal Yisroel.
Wishing all a K’siva V’chasima Tova for 5772.
