Is it possible to have withdrawal symptoms after a half of a day of not smoking cigarettes? I
I haven't smoked since this morning and now its 10:30 at night and my chest is tightening and its hard to breathe. I'm not sure if you can experience withdrawal symptoms that fast.

I quit smoking....I never went through chest tightening and not being able to breathe. Are you sure you're not just over-thinking this?

I don't know because today I feel the same way. I read in an article online about it but wasn't sure.

What were your withdraw symptoms if you don't mind me asking that

I don't remember mine but here are some from Google

• Headache.
• Nausea.
• Constipation or diarrhea.
• Falling heart rate and blood pressure.
• Fatigue, drowsiness, and insomnia.
• Irritability.
• Difficulty concentrating.
• Anxiety.

If you have any medical issues, such as high blood pressure, heart disease or diabetes and you are attempting to quit smoking, I would suggest you have a discussion with your doctor.
