When I was in university it got to the point where drinking tap water was difficult; forget orange juice, coffee and pasta sauce. In addition to the physical pain of consuming anything that was remotely acidic, the frequent (6-8/day) bowel movements of sometimes very bloody stool is what finally made me go visit my doctor.
Those days I was pulling all-nighters every week or so, sleeping 4-5 hours on nights where I actually went to bed, ate complete crap (typical university student), and hadn't done any sort of exercise other than walking to-and-from class for a solid 12 months. Yes, I was drinking 3-6 cups of coffee and/or energy drinks a day, but it was when I fixed all of the other stuff (mainly sleeping & eating better) that I started to not feel like death every day.
