I mentioned to my OB that I had been taking colace and he grimaced and asked if I thought it was doing anything for me. I wasn't joing much. Darn - I really liked the convenience of those little pills.
He recommended miralax in addition to fiber and water - said to take everyday until I was sure everything cleared up, then back of dosing until hit a happy place. It took about a week to feel like I had reached my max dose. My system was pretty happy for almost a week after that - just had to start up again.
I used to go to costco for wine and goat cheese. This week, I went for miralax, tums, and bio oil.
Good luck!
