It's very natural to have increased levels of anxiety in the early stages of quitting. I was a nervous wreck for a good portion of the first month of my quit so I just had to wait it out, knowing it would get better at some point and guess what ............. it did
Don't listen to that voice in your head telling you that smoking will fix your anxiety. That's not true. You are still in the very early part of your quit and your brain hasn't retrained itself to deal with day to day life as a non-smoker - hence the increased anxiety. What to do with all that extra time you have now. How to deal with being happy or sad and not including smoking. How to deal with stressful situations without smoking. The list goes on and on. This process of your brain retraining itself WILL happen but it takes time so, do whatever you have to but just don't smoke.
If you smoked a cigarette right now, it would NOT be the pleasurable mecca you think it would be. The taste would be horrible, you would likely choke and cough. Emotionally, you would regret it as soon as you had done it because your shiny 7 day quit would be gone! And, within 30 minutes of finishing that cigarette, your brain would be screaming for more nicotine. Remember? You're an addict and you would be re-introducing nicotine back into your body again - don't do it!!
Would you really want to ever go through those first 7 days of quitting again as well?
We all go through this stuff Shanakor and so can you. Stay committed and it WILL get better.
