There must be something about that 7 or 8 month mark. After the first couple of months of my quit, I was feeling very strong and confident. Then, around my 8th month, I was taken completely off guard by continual strong thoughts of smoking that lasted an entire weekend. I didn't smoke but I was quite pissed that I was still getting those feelings to light up.
As others have said, the first year is filled with all kinds of seasonal triggers but your quit gets stronger as you fight through them. And, it does get much easier with time.
You are doing great, Jo. These speed bumps will happen but just fight through them and don't light up.
