stea

I am having problems with constipation. I eat spinach, by choice at least 4-5 x a week, I take Benefiber 3 x a day, drink 4- 50 oz of water, exercise twice a week, and walk 30 minutes 3 x a week. I was banded 8-28-08, I have gone up to 11 days w/out a BM. I do not feel uncomfortable, it's only when I do move my bowels that I have such a difficult, uncomfortable time. My doctor told me not to use Milk of Magnesium. Help...
