Caffeine can affect your heart. Some people are more sensitive to it than others. My suggestion is to slowly stop drinking anything with caffeine. A friend of mine had heart problems but would not stop drinking drinks with caffeine and ended up dead due to an erratic heart rhythm. He would drink a pot of coffee in the morning and a six pack of coke in the afternoon. He would call his six pack a way to come down from the morning's coffee. Was it the caffeine? We will never know but I'm sure it did not help? https://www.webmd.com/heart-disease/news/20211115/coffee-can-affect-your-hearts-rhythms https://www.webmd.com/heart-disease/news/20211115/coffee-can... Lastly, ALWAYS consult your doctor before you change anything. They understand your situation and will be able to give you the best advice vs random people on the internet (me included).
