Do you know if Meta Fiber Wafers are as effective as psyllium powder? I have been taking psyllium capsules but my surgeon today said she does not recommend capsules because she is not certain that they break down quickly enough for my "rapid transit system". I have used them for some time because they are easier for travel and dining out. I would now begin using the powder form at home and the wafers for travel. Your experiences and comments will help guide my decision. Thank you!
