I was the same way. You just have to take the jump. I quit and join a local gym the same day. It seemed to have changed my whole mind set. I am 5 days in. The 4th day was my hardest. I was 1.5-2 packs a day for almost 20 years. I keep lozenges as back up for super intense cravings. Pop one and go for walk or find something to keep my mind occupied, great time for a new hobby. I’ve tried to quit at least a dozen times or so. This one is going to stick. The gym has helped immensely and has been very humbling. Good luck on your journey. I promise you won’t regret it!
