Now, I certainly cannot tell you what to do. My job here is to provide you health information for topics such as this. I also look to encourage you to reflect upon your own caffeine drinking habits. Is drinking a cup of coffee a day going to kill you? No, but if you’re going above that limit I would be careful. Maybe it’s actually hurting you more than helping you. Try trading that coffee mug for a water bottle. U of T has a large number of water filling stations across campus (no comment on 665). That’s it today for SWS, have a good rest of your weekend. Stay classy!
