If your bowel movements are too wide it is an indication that you are constipated. Your large intestine has stretched out over the years to handle all the stool. You can have several bowel movements a day and still be constipated.
I also think you should see a gastroenterologist to help you find something you can use daily and something you can tolerate.
You can get back to normal- it may take some time.
I also have had to deal with it- still working on finding the magic combination!
