In the first hour after swearing off smoking, your pulse rate and blood pressure will start to reduce, Llinos said.
But the craving for another cigarette might sneak up on you pretty quickly.
4 to 8 hours
Now a few hours into your no-smoke challenge, your oxygen levels should be recovering, and the harmful levels of carbon monoxide will reduce by half, Llinos went on.

It's now half a day since you stubbed out your last cigarette and you may be feeling sad and restless as the physical craving for another takes hold.
"These feelings won't last forever," Llinos said.
"Though you may feel a temporary relief if you smoke again, studies show depression and stress levels are lower when people stop smoking."
24 hours
A day in, you may notice yourself becoming more irritable and anxious.
"Please remember this is a temporary effect," the clinical services sister noted.
"Overall, it’s proven that mood, stress, anxiety and depression improve after stopping smoking."
2 to 3 days
After two or three days, all the carbon monoxide should be flushed out of your system.
Your lungs will also be clearing out the mucus and your sense of taste and smell will be improving.
But you may notice your appetite increases as you mistake cigarette cravings for hunger pangs.
4 to 5 days
After four or five days, your breathing becomes easier as your bronchial tubes start to relax, according Llinos.
On top of that, you may feel your energy levels rising.
5 to 7 days
After you've completed a week without smoking, your body no longer craves nicotine.
Llinos told Sun Health: "Now it is a case of ‘mind over matter’ and to stop smoking for good."
Two weeks
Two weeks in, your circulation will have improved.
Meanwhile, "as blood pumps through your heart and muscles much more efficiently, you will see an increase in your physical energy levels", Llinos added.
One month
One of the hallmarks of being a smoker is the persistent cough that plagues you throughout the year.
"You may notice that persistent cough, feeling of breathlessness or the annoying wheeze will improve as there is an improvement in your lung health," the health expert noted.
Three months
At three months, your lung function will have increased by 10 per cent.
One year
If you make it a year without smoking, your risk of heart disease and suffering a heart attack will decrease by 50 per cent, according to Llinos.
10 years
Now multiply that by 10, which is no mean feat!
