[iVTEC_Do_You?]

Hey guys, my stomach has been bothering me for the last 2 days, constantly cramping and aching every 10-20 minutes, forcing me to go to the washroom constantly. Bowel movements have been minimal. I saw a doctor today and he told me that I should be fine within a couple days but it's getting pretty bad as I can't sit comfortably for even 20 minutes without having these pains. I'm using Pepto-Bismol but it hasn't helped in the slightest. Anybody have experience with this kind of problem or have any ideas for remedies? I'd wait this out but I have a lot of things to do and this discomfort really hinders me.
Thanks in advance
