TRYING to give up coffee

I love coffee I have loved coffee since I was about 6 years old. I drink over a pot a day, I love flavored creamer but stopped using that bc of the empty calories so I drink it black. Cutting out coffee will give me at the min. 24 calories a day to use on something healthy
I am hoping I caN DO IT. But already feeling sluggish. I have made a pot of green tea that has no calories in it. Even that warm liqid it is still hard bc I have loved coffee so much.
I think tomorrow I will make 4 cups of coffee for am and then a pot of tea so I am not so sluggish. does that sound good or should I TRY to give it up cold turkey like I was thinking I was going to do. Please give me strength to give a love up.
