Giving up coffee is easy if you don’t give up caffeine 
I just did this a month or two ago - switched to Celestial Seasonings’ Morning Thunder tea (Black tea/Yerba Mate, which is a handy appetite supressant and makes a really tasty morning tea - I buy it on Amazon, but you can often find it at the Whole Foods and Natural Grocers stores). I use 2 tea bags and brew it strong in a tall latte mug, then add a tblsp of butter to emulsify it, and a tblp of coconut oil for my brainz, along with a splash of cream.
I’m experimenting with how eliminating coffee’s alkalanoids and mold toxins can help the body speed recomp. And I have to say it has sped things up, and I feel great! Some people recommend Green tea instead of Black, but I love the Black with Mate. 
Years and years ago, I gave up coffee & caffeine unexpectedly at a mountain retreat that served none and I’d brought none. Going through caffeine withdrawal at a high altitude was rather hellish - wouldn’t wish it on anyone. The slow caffeine reduction is much kinder, indeed.
