Hi Jewel :) Glad you are on here interacting with us all. It really does help and we have all been there so we truly do understand.
You are coming up to the 1 month mark which is Great but, still pretty early in your quit. You will still have up and down days for a while but those really will start to smooth out for you more and more all the time now and will become easier to deal with too. The anxiety will also fade gradually. Sooner for some and later for others but it will settle down eventually for you.
I still think of smoking as well at times like; oh gee I miss doing it at times and I miss the taste too at times but then I think of the realities and that snaps me out of my daydream pretty quickly. There are so many stories I have read about people with pretty long term quits who have givin in to similar thoughts which leads them to relapse. I read the same thing every time. The regret and the shame they feel afterward is incredible. I just know, I never want to experience that myself so I hold the memory of those stories in my head always so I don't get trapped into a similar relapse situation.
The other thing I think about when I'm thinking I might like to smoke again is that we always seem to remember the good things and never the bad about past experiences. Sort of like an old failed relationship. Oh, wouldn't it be nice to still be with so & so. We had such fun times together! Yes, that's probably true but there was also some other stuff that lead you to split and you've now forgotten just how intense that was.
Anyway, you're doing great so keep it up and focus on all the good things you are starting to notice since you've quit :)
