It started with crazy canker sores all over my tongue and a few pimples. The timelines I read were fairly accurate (e.g. tastebuds coming back, etc), but the biggest struggle was breaking the pattern.
Vaping just wasn't the same from the ritual side, but I'm glad I quit tobacco itself. Unlike many, I have no plans to quit nicotine. For me it takes the edge off -- and I think a lot of people with depression and anxiety are in the same boat.
People who haven't quit smoking will never understand what its like to quit smoking -- but the same goes for any addiction.
As with most things, saying is significantly easier than doing.
I had so many friends who smoked, and our independent desires to quit were definitely not in sync. I don't doubt that this was one of the major factors in me drawing out my quitting process.
