What you are experiencing is not an uncommon reaction to coffee and does not indicate any disease. If you look at the positive side, a cup in the morning will facilitate a bowel movement and get you going for the day. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
