I don’t think I drink 20 cups of caffeine in a day. I also don’t think it’s terribly unhealthy, or simply unhealthy for that matter. I am only aware of 2 problems with coffee. One is not even applicable to adults. I will list them for your reference:
1) It is said to stunt growth (in children)
2) It’s a bladder irritant. (When consumed in large amounts)
The above issues are not very problematic health-wise.
