In the early days for me, there were more tough days than better days (probably the first 4-6 weeks for me). There were up and down days from there on but the up days started to outnumber the down days as time passed. It all happens so slowly it's hard to discern exactly when it gets better more than not. My point is, if you hang in there for the long run (as you say Gus; making up your mind that you're done with smoking) then it will just happen for you at some point. I was reasonably comfortable with the whole quit thing after 6 weeks or so but it was probably 7 months before I really knew that I was done for good with cigarettes. That's when I started to look with pity rather than envy at others who were smoking. That's when I knew I'd really turned the corner for good. My brain finally got it .... cigarettes were my enemy - not my friend!
