I expect my first baby in about 3 weeks (guess that at nearly the age of 41 the sleep depreviation will be tough) but luckily due to shift work I am used to being tired (eg with nightshifts after a few hours of sleep I am awake already, tired but awake, or I have a late shift followed by an early shift and this also is maybe 5 hours of sleep).

I discovered that when doing a small workout I feel better. So I plan on just sticking to the PM. When my wife and baby takes a nap I will go to the garage and do my workout. The next nap hour I can take a nap myself.

I think the PM is good for this period, it does not take up much time but does wonders.
