Is it possible to get antibiotic-associated colitis without diarrhea? i seem to match up with all the symptoms but that, after a hefty triple therapy.

Dangerous C. diff: Yes, unfortunately it is possible to have colitis without diarrhea and if you think you have this, you need to be checked today by a doctor. Sometimes a patient may take an antidiarrheal or the illness itself causes a temporary 'bowel paralysis' so this needs to be evaluated for. A host of screening tests can help the doc make this diagnosis - so I suggest calling your primary MD and go to an E.R.
