I realize this a very old topic but I have experienced very similar symptoms and I highly recommend the BRAT diet or Low Residue Diet. Keeping a food diary, any 1 subject notebook will suffice, designate each for one day, write down every single thing you ingest, whether it's a vitamin, or candy, or breath mints, or a beverage. All of these items will hopefully will begin to show an irritant to your GI track and in that case, avoid that beverage or food for a while.
One food item on the Low Residue Diet that nearly solidified my output was instant mashed potatoes. Don't know why but if I had a serving a day, my irritated and touchy gut (from having had a resection and my gall bladder removed on top of that) appreciated a simple and probably unhealthy (in the long run) processed food item. It was simply what my gut needed - at the time.
For the past 6 months I've had a new job and now work long, long days. Someone on these forums suggested Sudafed D, 12 hour/pseudoephedrine HCI, to control D and IBS. If I take one(prefer generic Kroger Brand) upon waking each day, I swear my output is solid and the # of times is greatly reduced. Try it, can't hurt. This is the medication that is kept behind the pharmacy counter, you need to be 18 to purchase it and have a valid driver's license. I even take it on my days off from work since it's really helped me feel almost normal.
