I'm 21 months today -21 months I say....
All those coming through it does get easier, if you're in your first week you may not believe me but it does. First 3 months I was on a bit of a high (needed to put some distance between me and day 1) then you have the next 6 months when you've quit, there's too much invested to risk going back to day 1 but at times the learning to live without a fag when something happens, you go for a meal, go for a drink, have your first holiday/trip brings a little nudge, easily dismissed.
The one year is a fantastic feeling as is every month thereafter - looking forward to a long time of smiling about having quit. Pat yourself on the back - you've quit.
