I live on a plant based diet except for salmon once a week. Magnesium Oxide will help, 1000mg in over the counter versions containing it, but I just took the vitamins. I eat oatmeal with 4 prunes and a TB of ground flax for breakfast. My smoothie mid morning is Fage fat=free yogurt, 1 TB ground flax, 1 TB almonds, 2 Dried figs, and 1/2 c almond milk. My lunch is a Dr. praeger black bean burger on a WASA cracker with avocado and salsa. My afternoon snack is homemade gluten free pumpkin/chocolate chip muffins with ground flax in them. My dinner is an all raw veggie salad. No bread or flour products except for the muffins I make and the WASA crackers. So gluten free plant base diet. I take 2 docusate sodium after dinner and 2 Senokot before bed. My colon became non-functional after 3 occurrences of Ovarian Cancer, 4 abdominal surgeries, and all the chemo.
