text: yes, you could have Irritable Bowl Sndrome.  I have it and it took us 5 months to figure out!  Your doctor would probably want a colonoscopy done, and I warn you they make you drink this nasty laxitive that will clear out whatever is left in your colon.  You will only be able to drink clear liquid the day before, broth, popscicles, jello that sort of thing but nothing red because it can temporarly stain the colon and make the doctor think you have internal bleeding. They generally knock you completly out and you may be a bit sore after words but its worth it to make sure you don't have something worse.\nPlease cut back on drinking too, it could be causing it and you will get liver problems in the future if you don't  slow down! \nGood luck
