Been there PP.... I used the patch myself the first 4 day's are the hardest, the craving's only last about 30 second's so fight them off one at a time with whatever works for you.I used to just convince myself I would have one later and just kept putting it off
You won't believe how your brain will fuck with you during this time and in the future just laugh it off...the biggest thing is try not to have one but if you do, don't trash the whole attempt keep going it's worth it. Here is a timeline
20 Minutes
In less time than it takes to watch a sitcom, your body’s already getting better. After 20 minutes, your pulse and blood pressure start to drop back to normal. And your hands and feet warm up to their usual temperature.
8 Hours
By the end of a work day, you have half the amount of nicotine and carbon monoxide in your blood. Why does that matter? Carbon monoxide is a chemical in cigarettes, and it crowds out oxygen in your blood. That causes problems from your muscles to your brain because they don’t get the oxygen they need.
12 Hours
Halfway through your first day, your carbon monoxide level is back to normal. And your heart will thank you. Now it doesn’t have to pump so hard to try to get enough oxygen to your body.
24 Hours
If you smoke a pack a day, you’re twice as likely to have a heart attack as a nonsmoker. But go one full day without a cigarette, and you’ve lowered your chances. That’s huge.
48 Hours
With 2 days down, treat yourself to something tasty. By this point, your senses of taste and smell get sharper as your nerve endings start to heal.
Your body’s also busy with a lot of cleanup. Your lungs kick out mucus and other gunk left from cigarettes. And you don’t have any more nicotine in your body.
This is also about the time when the toughest withdrawal symptoms show up. You might feel anxious, dizzy, hungry, or tired. You might get headaches or feel bored or depressed. It’s normal, but it’s also makes it a lot harder to keep from lighting up.
Day 3 you breathe easier and have more energy.Your lungs start to recover and keep getting better
2 Weeks - 3 Months
During this time, you make huge strides. You can do more because your lungs are stronger and clearer, and your blood flow has improved. You can exercise without getting as winded. And your risk of a heart attack goes down even more.
You’ve also made it through the hardest part of withdrawal.
Even so, you’ll probably still get cravings. Everyone has different triggers for wanting to smoke. You can’t stop all of them, but you can stick to your plan. Think about the money you’re saving. Or try 10 deep breaths, nice and slow.
3-9 Months
At this point, you can take deeper, clearer breaths. Instead of hacking, you cough in a helpful way that actually clears things out. That helps you get fewer colds and other illnesses.
You’ll also have more energy.
1 Year
At the end of year 1, treat yourself. You’ve reached a milestone. And your risk of heart disease is now half of what it was a year ago.
