Personally, I don't see anything wrong with having a cup of coffee every day. I do. I have for 50 years and have no intention of stopping. We live in a world where a lot of people think they should be vegan or caffeine-free or avoid certain foods, salt, sugar, white flour, etc. If your doctor wants you to stop using caffeine, have a conversation with her about it. Ask why. Find out if you can have a little bit, or if it's entirely forbidden. I'm 16 years out from surgery and my one-cup of coffee in the morning has never hurt me. In fact, if you look online, you'll find caffeine helps you have regular bowel movement (I can attest to that) and also regulate the number of times you urinate during the day.In other words, it aids in the REMOVAL OF WASTE from your body. Of course, caffeine can be abused, but I'm giving the middle finger to those people who say arbitrary shit like this without medical research to back them up. Just ask your doctor what's right for you and then obey.
