I have suffered from constipation for years, drinking enough water that my back teeth are usually floating. I put two teaspoons of sugar free, orange flavored MetaMucil in 8oz of water, stir and slam it first thing in the morning. Then another 8 oz of water and slam that right after. The results are incredible, effortless bowel movements, that completely empty my colon. I cannot say enough about how wonderful this product is.
