What’s the secret to quitting

I feel horrible on caffeine. Bad anxiety, mood swings, poor sleep, eye bags etc etc. I have so many reasons to quit but I just seem to fail every time I try. I have such an uneasiness that is hard to sit with whenever I quit. I’ve quit so many time over the last 2 years. Some times as much as 2 months but I always go back. It’s like I’m holding my breath when I quit and I long for that feeling of relief when I finally have caffeine again. I know it’s a net negative for me and I long to be like a year free from it. I’ve been on caffeine every day since I was 12 so I think my brain is extremely hardwired towards caffeine. I know it’s possible and I know if I could make it a year I would be so happy but I can’t get past the first (worst) 90 days. It just seems like a black hole that pulls me back in every time. I’m looking for good advice that helped those of you like me quit the stuff for good
