Night time diarrhea

Well, I'm on the toilet on and off for most of the day.  From the time I get up till about 3 pm is the worst, then it slows down in late afternoon and into the evening to a few episodes, but lately it's been waking me up around 4 in the morning, sometimes with several episodes.  I usually feel a slight urge before going to sleep, but when I go to the washroom, nothing comes out.   A CT scan revealed no change from a year ago.   I am border line anemic and also have border line cortisol levels.   I was on antibiotics several months ago but have been eating yogurt so the flora should be normalized by now.   I was and have been through a very stressful year.  Also, years ago,  I had a small bowel resection but the diarrhea never got better, it continued, so they treat me with Questran (Cholestramine) (Olestyr).  I have used it and still use it occasionally but it's not the best thing for a strictured bowel, I will take it one day, and it will alleviate the diarrhea, sometimes (not always)  but then I suffer more the following day with bowel irritation and acid reflux, don't ask me why?  My question, if it was bile acid diarrhea alone, wouldn't the medicine help all of the time? Some days when I take it, it doesn't stop, I just have more to get rid of.  I am wondering if the diarrhea I suffer from is the result of crohn's alone or just from the outpouring of bile acids into the large intestine?    Anyways the night time diarrhea started a few months ago, got better and now it's back?  Any suggestions?  Sorry that my post is all over the place. 

Thank you, I will look into the accupuncture and see how it can help. Thank you for the last sentence, you have no idea how I needed to hear that there is still hope, even after a long time.
