You should try the combination with metronidazole (Flagyl) if the cipro alone doesn't do. That's the most common antibiotics combination for treating pouchitis. I always have 400 mg Flagyl and 500 mg cipro twice a day (for breakfast and supper) when I have increased pouchitis problems.
Does your doctor suspect that you're dealing with a depression? He prescribes sleeping drugs that are mainly antidepressive medicine. I luckily had only once in my life a depression, but the medicine I was prescribed at that time hindered me from sleeping.
Have your blood levels been controlled? If you're always tired that may be a lack of iron or B12.
It's difficult to tell from your description, but I wouldn't worry so much about eating and drinking but about the reason for your problems, may it be pouchitis, a lack of something or both.
