As you know and others have also said, there's just some awful days we all go through during our early quits, whether that be first week or a little latter on. I recall a few of those days still myself. I was really unsure if I could drag myself through those days or not.
I must say, I think being on a quit smoking forum helped me a lot. Just knowing others had experienced the same thing and had made it through gave me that little bit of extra encouragement I needed to make my own way through those horrid days so hang in there @MLMR. You will be made whole again soon!
