Even with the lack of sleep from staying up too late, I feel fabulous today. I've definitely noticed this not lacking energy even after a late night as one of the benefits of being a non-smoker (and I've mentioned it before as well). I think the dragging and just dead tired feeling in the past was so much worse because in general I didn't have as much energy as a smoker (I'm guessing due to less oxygen circulating - more on this below) and also because of the "smokers hangover" I'd get when I'd inevitably smoke more cigarettes later into the night. Without these two compounding issues in play today, I just feel like I could have used a couple more hours of sleep, but I don't feel terrible, miserable or even bad. In fact, I still feel energetic. As a once in awhile thing, I think I'm fine to have some late nights without much consequence. That's great stuff for a night owl like me who sometimes has too much coffee at night.
Now about this hunch about oxygen and circulation and smokers and lack of energy - turns out that this is correct but is much better explained by someone who can get it right:
From this article (which says the same as countless others but is also well worth reading all the way through for even more good info, especially for the girls, emphasis mine):
What Happens to Your BodyAnyway, my point is that not smoking = more energy = one more good thing
When you smoke, carbon monoxide–the colorless, odorless, deadly gas present in car exhaust–passes immediately into your blood. Carbon monoxide binds to the oxygen receptor sites and “kicks out” the oxygen molecules in your red blood cells.
Hemoglobin–the protein that feeds oxygen to organs, tissues, and cells–is bound to the carbon monoxide and can no longer carry oxygen. This means there's less oxygen for energy; less oxygen means less energy.
At the same time, your body receives a dose of nicotine. Nicotine increases your heart rate–as much as 10 to 15 beats per minute–requiring more oxygen. If you're pregnant, less oxygen reaches the fetus to help it grow and develop.
As you continue to smoke, your body responds to the low oxygen levels by producing changes that can put you at risk of blood clots and heart disease.
Women with osteoporosis seem to be at higher risk of bone thinning if they smoke. Smoking apparently increases the rate of breakdown of estrogen, a hormone that helps protect women against osteoporosis. Slender women are at greater risk because fat cells produce a small amount of estrogen.
