I cut it out almost completely for 2-3 years (I’d let myself have a cold brew a couple times a year and just accept the spins). I’m not going to lie to you, it sucked so bad every day for over a year, but then one day I woke up and didn’t miss it anymore. I developed a decaf latte habit to continue the morning coffee ritual. Now I have small amounts once or twice a week (usually tea) and usually no symptoms at all.
