| Coffee != Caffeine && Caffeine != Coffee. Before I switched to drinking coffee, I used to drink carbonated caffeinated beverages like Coke and Pepsi. Up to twelve per day. I'm convinced that is what gave me diabetes. So, I switched to Diet Coke. But then I learned about all the bad chemicals in Diet Coke and Coke Zero, so I switched to coffee. I drank caffeinated coffee for a long time. Decades. Occasionally, I would get to a state where if I had too much coffee, I would get caffeine headaches. And if I didn't drink enough coffee, I would get caffeine headaches. And there was no gap between those two states. I'd have to completely decaffeinate for a while, before I could reset my system. A few years ago, I switched to cold brew coffee, because it has about 70% less acid than hot brew. That was much better for my stomach. Then about a year ago, I switched to decaf cold brew, because the caffeine was causing too many problems with my heart rate, and my four different blood pressure medications weren't able to keep me in a good enough state. So, I stopped drinking coffee altogether. Now, it's just plain water. And I do feel a lot better. No heart rate problems, no excess acid, etc.... Just my experience. YMMV. |
