I have been juicing with a nutri-bullet and it is doing wonders for my regularity. I also am taking a daily probiotic which is the equivalent of 2000 cups of yogurt that I am sure adds to the going. My doc told me to eat 120+ grams of protein a day. Did yours tell you to up your protein? Protein can cause constipation so mixing it with fiber is crucial. I am no expert, but I happen to be a veggie so protein intake is something that I have been dealing with for years.
Big Hugs! Best of luck on being regular without running to the potty. Merry Christmas!!
