Hey RT,
I was in your situation, dipped for over 30 years other that a couple of stoppages, one for almost 4 years. I knew I wanted to quit, but I couldn't do it on my own. I went for years before giving quitting another shot because I felt like I couldn't take another failed attempt. I found KTC and today I posted 1048 days. That sounds like a long time, but not nearly as long as I dipped. Just keep quitting one day at a time.
My phone number is available upon request if you need some support, just shoot me a pm.
