Having coffee everyday is not bad at all but it certainly can make you pee more often.
The coffee can actually benefit your heart health and decreases your risk of heart disease, heart attacks and strokes.
I drink around 12 cups of coffee per day everyday and I've always been healthy so you can safely drink 12 cups of coffee per day or even some more if you want too without health risks.
Although avoid drinking coffee within a few hours before going to bed if it has caffeine in the coffee because it can keep you awake at night.
Coffee is a very healthy drink and I could not go without my coffee for too long because I need it to give me energy in the daytime and keep me awake.
