Hi Tacitus and welcome
Like you l drank for years and years and didn't have any withdrawals when l quit. The hard thing for people like us is never forgetting that we have a problem, no cravings etc can easily lull you into a false sense of security and convince you that you never really had a problem to begin with. That's one of the biggest issues l deal with. The other is filling the abundance of free time l found myself with, boredom is the addicts enemy.
I have found that the body has an amazing capacity to heal itself so good luck there.
Best wishes
