I quit through a slow cut back process. Got down to about two analogs a day, those were in the morning. Went back to also having one at the end of the work day, went back to having two at the end of the work day.
A couple things helped me kick it all together.
Snus, I just grabbed some camel brand at the corner gas station. Helped huge at work because yeah, I had to get of the other chemical cravings smoking gave me. I used it when I felt a big foggy in the head instead of reaching for an analog.
Second, I was using a 510, I did up the nicotine but found myself liking the simplicity of just lighting up rather than recharging batteries, filling up carts etc etc....
I was getting frustrated, that's when my two a day analogs crept back up to around five a day.
Got an IM from a member who suggested I get a mod. I ordered them along with batteries and cartomizers. Since I went with a custom mod, chucks, I had a bit of a wait while it was being made. During my wait, I worked on cutting back down to just my morning analogs, wasn't easy, I live with a smoker. I told myself this is what is gonna get me over the analog hump and I was right. Within two days of vaping on a 3.7 mod with cartomizers I was able to give up analogs. I am only two weeks in, out of habit I still want an analog in the morning but not having one isn't painful like it was before.
It's a slow process but any progress is good and that is what you must remind yourself.
It seems everyone quits different so my post is just my two cents.
I've also dropped a pretty penny on various supplies and liquid. I think of it long term, I am in the hole if I compare my analog cost to vaping but the hole won't last and as each week/month goes by I will break even and start to go the other direction. Hopefully my life expectancy will do the same and that is what matters most.
