Congratulations @erikah! I stopped drinking coffee at home almost two years ago and I experienced the same. It was "rough" as you wrote in the beginning. I noticed that I was addicted to it too. Now I drink decaf at home and a cup or two regular coffee outside a month. I feel myself healthier and clearer :)
In that case congratulations to you too! It's definitely not easy but doable, if you have the necessary strength and determination. We won't regret it, trust me.
