I have not changed my diet at all. I pretty much eat whatever I want. I am still taking Miralax every once in a while but I am thinking about just getting off of it for a while to see if this Digestive Advan. will just do the trick by itself. I used to take Zelnorm too, but I have completely gotten off of that too. All I do is just chew up one DA and I go to the bathroom like a normal person. Oh yea, I still have some gas but it's not as bad as it used to be. I def dont feel as bloated and I think that is due to just being able to go to the bathroom everyday and getting rid of the pressure. I would definitely recommend just trying it for a week or two and see if it works. This is the absolute one thing I have found to work without making me cramp up and have D like Zelnorm and laxatives seemed to do to me. Hope it works for you! Let me know!
