Timeline?

I’ve been a constant user of 3mg zyns for about 6 years now if not longer. There’s not a moment throughout the day where I don’t have a zyn in my mouth. I work a pretty lax job and it’s pretty boring with a lot of sitting so it’s easy to toss one in and suck on it to pass the time. Been noticing some health issues lately troubles sleeping, digestive issues, and anxiety. Decided enough is enough and it’s time to stop. I decided to go cold turkey and just quit and get it done and over with. What type of timeline have people experienced? What has happened when in the timeline? And is there anything that people have done to make the symptoms less aggressive and the quit easier?

I have 13 days off work and I’m hoping the heavy symptoms are done by then because although I have a boring job it’s something where my mental capacity and overall health needs to be in top shape. I can’t exactly deal with sleep issues, or anxiety around the days I’m working. Thanks!
